【问题描述】:
我想使用 DataAdapter 填充 DataGridView 控件。但我不知道该怎么做,因为我使用的是带参数的存储过程。 有人可以举个例子吗?

这是一个 Microsoft article,它提供了一个这样做的例子。

我明白了!...呵呵
protected DataTable RetrieveEmployeeSubInfo(string employeeNo)
{
SqlCommand cmd = new SqlCommand();
SqlDataAdapter da = new SqlDataAdapter();
DataTable dt = new DataTable();
try
{
cmd = new SqlCommand("RETRIEVE_EMPLOYEE", pl.ConnOpen());
cmd.Parameters.Add(new SqlParameter("@EMPLOYEENO", employeeNo));
cmd.CommandType = CommandType.StoredProcedure;
da.SelectCommand = cmd;
da.Fill(dt);
dataGridView1.DataSource = dt;
}
catch (Exception x)
{
MessageBox.Show(x.GetBaseException().ToString(), "Error",
MessageBoxButtons.OK, MessageBoxIcon.Error);
}
finally
{
cmd.Dispose();
pl.MySQLConn.Close();
}
return dt;
}

Using块
SqlParameter param = new SqlParameter("@EMPLOYEENO", employeeNo); param.Direction = ParameterDirection.Input; cmd.Parameters.Add(param); 见@ 987654322@
SqlConnection con = new SqlConnection(@"Some Connection String");
SqlDataAdapter da = new SqlDataAdapter("ParaEmp_Select",con);
da.SelectCommand.CommandType = CommandType.StoredProcedure;
da.SelectCommand.Parameters.Add("@Contactid", SqlDbType.Int).Value = 123;
DataTable dt = new DataTable();
da.Fill(dt);
dataGridView1.DataSource = dt;

也许您的代码缺少 Microsoft 示例中的这一行:
MyDataAdapter.SelectCommand.CommandType = CommandType.StoredProcedure
【讨论】:
SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder();
builder.DataSource = <sql server name>;
builder.UserID = <user id>; //User id used to login into SQL
builder.Password = <password>; //password used to login into SQL
builder.InitialCatalog = <database name>; //Name of Database
DataTable orderTable = new DataTable();
//<sp name> stored procedute name which you want to exceute
using (var con = new SqlConnection(builder.ConnectionString))
using (SqlCommand cmd = new SqlCommand(<sp name>, con))
using (var da = new SqlDataAdapter(cmd))
{
cmd.CommandType = System.Data.CommandType.StoredProcedure;
//Data adapter(da) fills the data retuned from stored procedure
//into orderTable
da.Fill(orderTable);
}

又短又甜……
DataTable dataTable = new DataTable();
try
{
using (var adapter = new SqlDataAdapter("StoredProcedureName", ConnectionString))
{
adapter.SelectCommand.CommandType = CommandType.StoredProcedure;
adapter.SelectCommand.Parameters.Add("@ParameterName", SqlDbType.Int).Value = 123;
adapter.Fill(dataTable);
};
}
catch (Exception ex)
{
Logger.Error("Error occured while fetching records from SQL server", ex);
}

我们来了,
DataSet ds = new DataSet();
SqlCommand cmd = new SqlCommand();
cmd.Connection = con; //database connection
cmd.CommandText = "WRITE_STORED_PROC_NAME"; // Stored procedure name
cmd.CommandType = CommandType.StoredProcedure; // set it to stored proc
//add parameter if necessary
cmd.Parameters.Add("@userId", SqlDbType.Int).Value = courseid;
SqlDataAdapter adap = new SqlDataAdapter(cmd);
adap.Fill(ds, "Course");
return ds;

public DataSet Myfunction(string Myparameter)
{

config.cmd.Parameters.Add("parameter", SqlDbType.VarChar, 10);
config.cmd.Parameters["parameter"].Value = Myparameter;
config.dRadio = new SqlDataAdapter(config.cmd);
config.dRadio.Fill(config.ds,"Table");
return config.ds;
}
【讨论】:
SqlConnection con = new SqlConnection(@"Some Connection String");//connection object
SqlDataAdapter da = new SqlDataAdapter("ParaEmp_Select",con);//SqlDataAdapter class object
da.SelectCommand.CommandType = CommandType.StoredProcedure; //command sype
da.SelectCommand.Parameters.Add("@Contactid", SqlDbType.Int).Value = 123; //pass perametter

da.Fill(dt); //call the stored producer
