I know to get field size from a table by ado is as below:

Set Recordset = Server.CreateObject("ADODB.Recordset")
Recordset.Open "SELECT * FROM TABLE", connection
Size = Recordset.Fields("Field1").DefinedSize

But how to do the same for ado.net?
Please give a code example. Thanks

Hi limct,

'SQL Server Connection

Dim strSQL as string = "SELECT FirstName,LastName FROM Employees;"
Dim strConnection as String = "server=;database=Northwind; User Id=sa;password=;"

Dim objDataSet As New DataSet()
Dim objConnection As New SqlConnection(strConnection)

'create a new DataAdapter using the connection object and select statement
Dim objDataAdapter As New SqlDataAdapter(strSQL, objConnection)

'fill the dataset with data from the DataAdapter object
objDataAdapter.Fill(objDataSet, "Employees")

Dim Size as integer

Size = objDataSet.Tables("Employees").Columns("FirstName").Maxlength
