LINQ

I want to use linq to get datarow array from a datatable which its string type ColumnA is not null or depending on its length >0 , so I can get the row index with Indexof() method to deal with something else.

ColumnA ColumnB ColumnC
A0       B0       C0
Null     B1       C1
A2       B2       C2
Null     B3       C3

My Linq Statment:

DataRow[] rows =  myDataTable.Select("ColumnA is not null").Where(row=>row.Field<string>("ColumnA").Length>0);

somebody who can help?
