得到数据库存储过程列表：

select * from dbo.sysobjects where OBJECTPROPERTY(id, N'IsProcedure') = 1 order by name

得到某个存储过程的参数信息：(SQL方法)

select * from syscolumns where ID in
(SELECT id FROM sysobjects as a
   WHERE OBJECTPROPERTY(id, N'IsProcedure') = 1
   and id = object_id(N'[dbo].[mystoredprocedurename]'))

得到某个存储过程的参数信息：(Ado.net方法)

SqlCommandBuilder.DeriveParameters(mysqlcommand);

得到数据库所有表：

select * from dbo.sysobjects where OBJECTPROPERTY(id, N'IsUserTable') = 1 order by name

得到某个表中的字段信息：

select c.name as ColumnName, c.colorder as ColumnOrder, c.xtype as DataType, typ.name as DataTypeName, c.Length, c.isnullable from dbo.syscolumns c inner join dbo.sysobjects t
on c.id = t.id
inner join dbo.systypes typ on typ.xtype = c.xtype
where OBJECTPROPERTY(t.id, N'IsUserTable') = 1
and t.name='mytable' order by c.colorder;

C# Ado.net代码示例：

1. 得到数据库存储过程列表：

using System.Data.SqlClient;

private void GetStoredProceduresList()

    string sql = "select * from dbo.sysobjects where OBJECTPROPERTY(id, N'IsProcedure') = 1 order by name";

    string c style="color: #006080">@"Data Source=(local);Initial Catalog=mydatabase; Integrated Security=True; Connection Timeout=1;";

    SqlConnection c style="color: #0000ff">new SqlConnection(connStr);

    SqlCommand cmd = new SqlCommand(sql, conn);

    cmd.CommandType = CommandType.Text;

try

        conn.Open();

        using (SqlDataReader MyReader = cmd.ExecuteReader())

            while (MyReader.Read())

                //Get stored procedure name

                this.listBox1.Items.Add(MyReader[0].ToString());

    finally

        conn.Close();

2. 得到某个存储过程的参数信息：(Ado.net方法)

using System.Data.SqlClient;

private void GetArguments()

    string c style="color: #006080">@"Data Source=(local);Initial Catalog=mydatabase; Integrated Security=True; Connection Timeout=1;";

    SqlConnection c style="color: #0000ff">new SqlConnection(connStr);

    SqlCommand cmd = new SqlCommand();

    cmd.C >    cmd.CommandText = "mystoredprocedurename";
    cmd.CommandType = CommandType.StoredProcedure;
 
    try
    {
        conn.Open();
 
        SqlCommandBuilder.DeriveParameters(cmd);
 
        foreach (SqlParameter var in cmd.Parameters)
        {
            if (cmd.Parameters.IndexOf(var) == 0) continue;//Skip return value
 
            MessageBox.Show((String.Format("Param: {0}{1}Type: {2}{1}Direction: {3}",
               var.ParameterName,
               Environment.NewLine,
               var.SqlDbType.ToString(),
               var.Direction.ToString())));
        }
    }
    finally
    {
        conn.Close();
    }
 
}

3. 列出所有数据库：

using System;

using System.Windows.Forms;

using System.Collections.Generic;

using System.Text;

using System.Data;

using System.Data.SqlClient;

private static string c >            "Persist Security Info=True;timeout=5;Data Source=192.168.1.8;User ID=sa;Password=password";
 
/// <summary>
/// 列出所有数据库
/// </summary>
/// <returns></returns>
public string[] GetDatabases()
{
    return GetList("SELECT name FROM sysdatabases order by name asc");
}
 
private string[] GetList(string sql)
{
    if (String.IsNullOrEmpty(connString)) return null;
 
    string c > 
    SqlConnection c style="color: #0000ff">new SqlConnection(connStr);
    SqlCommand cmd = new SqlCommand(sql, conn);
    cmd.CommandType = CommandType.Text;
 
    try
    {
        conn.Open();
 
        List<string> ret = new List<string>();
 
        using (SqlDataReader MyReader = cmd.ExecuteReader())
        {
            while (MyReader.Read())
            {
                ret.Add(MyReader[0].ToString());
            }
        }
 
        if (ret.Count > 0) return ret.ToArray();
        return null;
    }
    finally
    {
        conn.Close();
    }
}

4. 得到Table表格列表：

private static string c >  "Persist Security Info=True;timeout=5;Data Source=192.168.1.8;Initial Catalog=myDb;User ID=sa;Password=password";
 
/* select name from sysobjects where xtype='u'  ---
   C = CHECK 约束
   D = 默认值或 DEFAULT 约束
   F = FOREIGN KEY 约束
   L = 日志
   FN = 标量函数
   IF = 内嵌表函数
   P = 存储过程
   PK = PRIMARY KEY 约束（类型是 K）
   RF = 复制筛选存储过程
   S = 系统表
   TF = 表函数
   TR = 触发器
   U = 用户表
   UQ = UNIQUE 约束（类型是 K）
   V = 视图
   X = 扩展存储过程
   */
 
public string[] GetTableList()
{
    return GetList("SELECT name FROM sysobjects WHERE xtype='U' AND name   <>   'dtproperties' order by name asc");
}

5. 得到View视图列表：

public string[] GetViewList()

     return GetList("SELECT name FROM sysobjects WHERE xtype='V' AND name   <>   'dtproperties' order by name asc");

6. 得到Function函数列表：

public string[] GetFunctionList()

    return GetList("SELECT name FROM sysobjects WHERE xtype='FN' AND name   <>   'dtproperties' order by name asc");

7. 得到存储过程列表：

public string[] GetStoredProceduresList()

    return GetList("select * from dbo.sysobjects where OBJECTPROPERTY(id, N'IsProcedure') = 1 order by name asc");

8. 得到table的索引Index信息：

public TreeNode[] GetTableIndex(string tableName)

    if (String.IsNullOrEmpty(connString)) return null;

    List<TreeNode> nodes = new List<TreeNode>();

    string c > 
    SqlConnection c style="color: #0000ff">new SqlConnection(connStr);
    SqlCommand cmd = new SqlCommand(String.Format("exec sp_helpindex {0}", tableName), conn);
    cmd.CommandType = CommandType.Text;
 
    try
    {
        conn.Open();
 
        using (SqlDataReader MyReader = cmd.ExecuteReader())
        {
            while (MyReader.Read())
            {
                TreeNode node = new TreeNode(MyReader[0].ToString(), 2, 2);/*Index name*/
                node.ToolTipText = String.Format("{0}{1}{2}", MyReader[2].ToString()/*index keys*/, Environment.NewLine,
                    MyReader[1].ToString()/*Description*/);
                nodes.Add(node);
            }
        }
    }
    finally
    {
        conn.Close();
    }
 
    if(nodes.Count>0) return nodes.ToArray ();
    return null;
}

9. 得到Table，View，Function，存储过程的参数，Field信息：

public string[] GetTableFields(string tableName)

    return GetList(String.Format("select name from syscolumns where id =object_id('{0}')", tableName));

10. 得到Table各个Field的详细定义：

public TreeNode[] GetTableFieldsDefinition(string TableName)

    if (String.IsNullOrEmpty(connString)) return null;

    string c > 
    List<TreeNode> nodes = new List<TreeNode>();
 
    SqlConnection c style="color: #0000ff">new SqlConnection(connStr);
    SqlCommand cmd = new SqlCommand(String.Format("select a.name,b.name,a.length,a.isnullable from syscolumns a,systypes b,sysobjects d where a.xtype=b.xusertype and a.id=d.id and d.xtype='U' and a.id =object_id('{0}')",
                  TableName), conn);
    cmd.CommandType = CommandType.Text;
              
    try
    {
        conn.Open();
 
        using (SqlDataReader MyReader = cmd.ExecuteReader())
        {
            while (MyReader.Read())
            {
                TreeNode node = new TreeNode(MyReader[0].ToString(), 2, 2);
                node.ToolTipText = String.Format("Type: {0}{1}Length: {2}{1}Nullable: {3}", MyReader[1].ToString()/*type*/, Environment.NewLine,
                    MyReader[2].ToString()/*length*/, Convert.ToBoolean(MyReader[3]));
                nodes.Add(node);
            }
        }
 
        if (nodes.Count > 0) return nodes.ToArray();
        return null;
    }
    finally
    {
        conn.Close();
    }
 
}

11. 得到存储过程内容：

类似“8. 得到table的索引Index信息”，SQL语句为：EXEC Sp_HelpText '存储过程名'

12. 得到视图View定义：

类似“8. 得到table的索引Index信息”，SQL语句为：EXEC Sp_HelpText '视图名'
