Let us create a datatable as under
Private Function MyDataTable() As DataTable
Dim dtsource As New DataTable("Details")
'Adding columns to datatable
dtsource.Columns.Add("Name", GetType(String))
dtsource.Columns.Add("Gender", GetType(Boolean))
'Adding records to the datatable
dtsource.Rows.Add("Name1", 1)
dtsource.Rows.Add("Name2", 1)
dtsource.Rows.Add("Name3", 0)
dtsource.Rows.Add("Name4", 1)
dtsource.Rows.Add("Name5", 0)
Return dtsource
End Function
Then fire the below query
Dim dt = MyDataTable().AsEnumerable().[Select](Function(dr) New With { _
Key .Name = dr.Field(Of String)("Name"), _
Key .Category = dr.Field(Of Boolean)("Gender"), _
Key .NewCategory = If(dr.Field(Of Boolean)("Gender"), "Male", "Female") _
}).ToList()
We are using the
AsEnumerable() extension method which is available in
System.Data.DataSetExtensions assembly.
