'dataType' argument cannot be null.

[Saturn57]

I have the following code that is throwing the error ('dataType' argument cannot be null.
Parameter name: dataType)

Code:
Dim dt As New DataTable
dt.TableName = "WorkRelease"
dt.Columns.Add("JobNo", System.Type.GetType("System.Data.SqlTypes.SqlString"))

DataTables aren't tied to a specific database or dialect, so the proper syntax is the following

Dim dt As New DataTable
        dt.TableName = "WorkRelease"
        dt.Columns.Add("JobNo", System.Type.GetType("System.String"))
