如何为日期类型传递输出参数

Question

I need to have output parameter which data type is date on vb.net. I know how to do it for integer. Would someone tell me how to do it for date. I am not sure the size.

 paramOut = New SqlParameter("@OrderID", SqlDbType.Int, 4, ParameterDirection.InputOutput, True, 10, 0, "@OrderID", DataRowVersion.Current, DBNull.Value)

Answer 1

No need to specify size at all. Do this

VB.NET

Dim outputParm As New SqlParameter With {
    .Direction = ParameterDirection.Output,
    .ParameterName = "@OrderID",
    .SqlDbType = SqlDbType.Date}
command.Parameters.Add(outputParm)

---

C#

 SqlParameter outputParm = new SqlParameter { Direction = System.Data.ParameterDirection.Output, ParameterName = "@OrderID", SqlDbType = System.Data.SqlDbType.Date }; command.Parameters.Add(outputParm); 

Answer 2

试试SqlDbType.DateTime 这里是那些数据成员的很好参考
