C# 调用存储过程

CREATE PROC P_TEST
@Name VARCHAR(20),
@Rowcount INT OUTPUT
AS
BEGIN
 SELECT * FROM T_Customer WHERE NAME=@Name
 SET  @Rowcount=@@ROWCOUNT
END
GO

using System.Data.SqlClient;
......
 private void Page_Load(object sender, System.EventArgs e)
  {
   // 在此处放置用户代码以初始化页面
   String DBConnStr;
   DataSet MyDataSet=new DataSet();
   System.Data.SqlClient.SqlDataAdapter DataAdapter=new System.Data.SqlClient.SqlDataAdapter();
   DBConnStr=System.Configuration.ConfigurationSettings.AppSettings["ConnectString"];
   System.Data.SqlClient.SqlConnection myConnection = new System.Data.SqlClient.SqlConnection(DBConnStr);
   if (myConnection.State!=ConnectionState.Open) 
   {
    myConnection.Open();
   }   
   System.Data.SqlClient.SqlCommand myCommand = new System.Data.SqlClient.SqlCommand("P_Test",myConnection);
   myCommand.CommandType=CommandType.StoredProcedure;
   //添加输入查询参数、赋予值
   myCommand.Parameters.Add("@Name",SqlDbType.VarChar);
   myCommand.Parameters["@Name"].Value ="A";

   //添加输出参数
   myCommand.Parameters.Add("@Rowcount",SqlDbType.Int);
   myCommand.Parameters["@Rowcount"].Direction=ParameterDirection.Output;


   myCommand.ExecuteNonQuery();
   DataAdapter.SelectCommand = myCommand;

   if (MyDataSet!=null)
   {
     DataAdapter.Fill(MyDataSet,"table");
   }
   
   DataGrid1.DataSource=MyDataSet;
   DataGrid1.DataBind();
   //得到存储过程输出参数
   Label1.Text=myCommand.Parameters["@Rowcount"].Value.ToString();

   if (myConnection.State == ConnectionState.Open)
   {
    myConnection.Close();
   }

  }

运行以上代码即可(返回记录集合和存储过程返回值)
