Garabage collection error on a datatable

I have the following DataTable. While i am trying to add rows to this data table it returns an error like this

Cannot evaluate expression because a thread is stopped at a point where garbage collection is impossible, possibly because the code is optimized.

Does the DataTable has any memory limits?

dtOrder = new DataTable();
    dtOrder.Columns.Add(new DataColumn("sl_Odr_ID", 开发者_如何学Pythontypeof(long)));
    dtOrder.Columns.Add(new DataColumn("pack_dtl_ID", typeof(int)));
    dtOrder.Columns.Add(new DataColumn("Name", typeof(string)));
    dtOrder.Columns.Add(new DataColumn("sales_Batch_No", typeof(string)));
    dtOrder.Columns.Add(new DataColumn("sales_Qty", typeof(decimal)));
    dtOrder.Columns.Add(new DataColumn("sales_free", typeof(int)));
