Issue in Code Stage using DataTable as Variable

MohiniShelke · ‎19-07-19

Hi Team,

I am using c# linq query of group in Code Stage,

But, I am getting following error.

Description: Compiler error at line 1: 'System.Data.DataTable' does not contain a definition for 'AsEnumerable' and no extension method 'AsEnumerable' accepting a first argument of type 'System.Data.DataTable' could be found (are you missing a using directive or an assembly reference?)
Repairable: No

Please let me know the solution for this?

Thanks in advance

You're missing a namespace. I think that specific error is if you're missing the generic collections namespace. Can't remember.

Try making sure you have these at least:

External References:

System.dll
System.Data.dll
System.Xml.dll
System.Drawing.dll
System.Core.dll
System.Data.DataSetExtensions.dll

Namespace Imports:

System
System.Drawing
System.Data
System.Collections.Generic
System.Linq

Edit: One or two of those may be unnecessary depending on what you're doing with it, but it won't hurt to add them all.

Thank David Morris

It works fine but another error occurs as follws:

Description: Compiler error at line 0: The out parameter 'ColumnValues' must be assigned to before control leaves the current method
Repairable: No
My Code :

var grouped = from table in InputCollection.AsEnumerable()var grouped = from table in InputCollection.AsEnumerable()group table by new { placeCol = table["Place"]
} into groupby select new{Value = groupby.Key,ColumnValues = groupby,};

Thanks

What is datatype of ColumnValues?

if it's collection set this at beginning ColumnValues=new System.Data.DataTable();
if it's text set this at beginning ColumnValues=String.Empty;
