dotnet中调用存储过程的用法，包含事务处理

簡單的存儲過程如下：


using System;


using System.Data;


using System.Data.OleDb;


using System.Configuration;


using System.Collections;


using System.Web;


using System.Web.Security;


using System.Web.UI;


using System.Web.UI.WebControls;


using System.Web.UI.WebControls.WebParts;


using System.Web.UI.HtmlControls;


using System.IO;


using System.Drawing;


using System.Reflection;


using System.Runtime.InteropServices;


using Microsoft.Office.Interop.Excel;


using System.Data.Common;


using Microsoft.Practices.EnterpriseLibrary.Common;


using Microsoft.Practices.EnterpriseLibrary.Configuration;


using Microsoft.Practices.EnterpriseLibrary.Data;








public partial class TaskAdministration_test : System.Web.UI.Page




...{


protected void Page_Load(object sender, EventArgs e)




...{






}




protected void Button1_Click(object sender, EventArgs e)




...{


ExcelOperation OEM = new ExcelOperation();


string isCommit = "Y";


Database db = DatabaseFactory.CreateDatabase();


DbConnection tconn = db.CreateConnection();


DbCommand cmd = tconn.CreateCommand();


DbCommand cmd1 = tconn.CreateCommand();


tconn.Open();


DbTransaction ttran= tconn.BeginTransaction();


cmd.Connection = ttran.Connection;


cmd1.Connection = ttran.Connection;


cmd.Transaction = ttran;


cmd1.Transaction = ttran;


try




...{


cmd.CommandText = "PR_INSERTDM";


cmd.CommandType = CommandType.StoredProcedure;


OEM.AddInParameter(cmd, "ptaskid",txt1.Text);


OEM.AddInParameter(cmd, "proleid", txt2.Text);


OEM.AddInParameter(cmd, "pmembername", txt3.Text);


cmd.ExecuteNonQuery();




cmd1.CommandText = "PR_INSERTDT";


cmd1.CommandType = CommandType.StoredProcedure;


OEM.AddInParameter(cmd1, "PTASKID", txt4.Text);


OEM.AddInParameter(cmd1, "PROLEID", txt5.Text);


OEM.AddInParameter(cmd1, "PDEPTNAME", txt6.Text);


cmd1.ExecuteNonQuery();


}


catch(Exception ex)




...{


isCommit = "No";


tconn.Close();


}


finally




...{


if (isCommit == "No")




...{


ttran.Rollback();


throw new Exception("操作失敗!");


}


else




...{


ttran.Commit();


}


tconn.Close();


}


}


}



説明：1.存儲過程和類都比較簡單,目的是盡量簡單的説明在事務中調用多個存儲過程的用法.

2.可能有比這個更好的代碼,如果願意你可以發表你的評論,我很樂意接受.
