本文实例讲述了C# Ado.net读取SQLServer数据库存储过程列表及参数信息的方法。分享给大家供大家参考，具体如下：
得到数据库存储过程列表：
|
1
|
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)
|
1
2
3
4
|
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)
|
1
|
SqlCommandBuilder.DeriveParameters(mysqlcommand); |
得到数据库所有表：
|
1
|
select * from dbo.sysobjects where OBJECTPROPERTY(id, N'IsUserTable') = 1 order by name |
得到某个表中的字段信息：
|
1
2
3
4
5
|
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 ton c.id = t.idinner join dbo.systypes typ on typ.xtype = c.xtypewhere OBJECTPROPERTY(t.id, N'IsUserTable') = 1and t.name='mytable' order by c.colorder; |

public TreeNode[] GetTableFieldsDefinition(string TableName){ if (String.IsNullOrEmpty(connString)) return null; string connStr = connString; List<TreeNode> nodes = new List<TreeNode>(); SqlConnection conn = 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'
(以上代码可用于代码生成器，列出数据库的所有信息)
希望本文所述对大家C#程序设计有所帮助。
