怎样写一个存储过程类来实现C#中对存储过程的调用？

假设数据表为UserDataStore，存储过程InsertUserData如下：

CREATE PROCEDURE InsertUserData 
@UserName NVARCHAR(50) = NULL, 
@UserInfo NVARCHAR(4000) = NULL 

AS 
SET XACT_ABORT ON 
BEGIN TRANSACTION 
INSERT INTO [UserDataStore] 
VALUES (@UserName,@UserInfo) 
COMMIT TRANSACTION 
RETURN 0 
GO

则相应的程序为：

public bool InsertUserData(DataSet userData) 
{ 
	OleDbCommand insertCommand=new OleDbCommand("InsertUserData",dsConnection); 
	insertCommand.CommandType=CommandType.StoredProcedure; 
	insertCommand.Parameters.Add("@UserName",OleDbType.VarWChar,50,"UserName"); 
	insertCommand.Parameters.Add("@UserInfo", OleDbType.VarWChar,4000,"UserInfo"); 
	dsCommand.InsertCommand=insertCommand; 
	try 
	{ 
		dsCommand.InsertCommand=this.GetInsertCommand(); 
		dsCommand.Update(userData,"UserDataStore"); 
		userData.AcceptChanges(); 
		return (true); 
	} 
	catch(Exception e) 
	{ 
		throw e; 
	} 
}
