--存储过程调用如下:

DECLARE @i INT

EXEC P_TEST 'A',@i OUTPUT

SELECT @i

--结果

--C#代码:(用到两个测试控件,DataGrid1(用于显示绑定结果集合),Lable(用于显示存储过程返回单值)

代码

复制代码 代码如下:

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();

}

}
