Question

我正在尝试在vb.net中创建一些将参数传递给SQL Server 2008中的存储过程的应用程序我试过这段代码，我不确定下一步应该写什么

Public Function List(ByVal date As Date) As DataTable
    Dim SPName As String = "usp_Name"
    Dim dt As New DataTable
    Try
        oConn.Open()
        Dim cmdSQL As New SqlCommand(SPName, oConn)
        cmdSQL.CommandTimeout = 2000
        cmdSQL.CommandType = CommandType.StoredProcedure
        cmdSQL.Parameters.Add("@Date").Value = date //im not really sure this is the correct code
        Dim da As New SqlDataAdapter(cmdSQL)
        da.Fill(dt)
    Catch ex As Exception
        MessageBox.Show(ex.ToString)
    Finally
        oConn.Close()
    End Try

End Function
