SelectCommand属性还没有被调用初始化之前“补”

运行StoredProcedure.ExecuteDataSet（）时，我得到这个错误;

 DataSet ds= new DataSet();
        SqlDataAdapter ada = new SqlDataAdapter();
        try
        {
            ada.Fill(ds);
        }
        catch { }

Answer 1:

我能够通过添加以下代码来解决这个问题：

[162] DbDataAdapter da = Factory.CreateDataAdapter();
[163] da.SelectCommand = cmd; < - 添加此
[164] da.Fill(ds);

希望这可以帮助，如果其他人有这个问题？

Answer 2:

我是有这个问题，该行由它的工作....

Protected Sub searchButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles searchButton.Click
    Try
        Dim dt As New Data.DataTable
        Dim con As New SqlConnection(ConfigurationManager.ConnectionStrings("connection1").ToString())
        Dim cmd As New SqlCommand("getAllPerson", con)
        cmd.CommandType = Data.CommandType.StoredProcedure

        cmd.Parameters.Add("@id", Data.SqlDbType.Int).Value = CInt(SearchBox.Text)

        Dim da As New SqlDataAdapter
        da.SelectCommand = cmd
        da.Fill(dt)

        fnameTextBox.Text = dt.Rows(0).Item("FName")
        lnameTextBox.Text = dt.Rows(0).Item("LName")
        dobTextBox.Text = dt.Rows(0).Item("DOB")
        addressTextBox.Text = dt.Rows(0).Item("Address")
        address1TextBox.Text = dt.Rows(0).Item("Address1")
        contactTextbox.Text = dt.Rows(0).Item("ContactNo")
    Catch ex As Exception
        MsgBox(ex.Message.ToString())
    End Try

End Sub
