Rajeev Pentyala – Microsoft Power Platform

I was getting below error while querying “AccountSet” using LINQ in my plug-in

System.InvalidOperationException: Sequence contains no elements

Reason:-

• Exception raised when there were no records that matches to the criteria specified in my LINQ query
• I had my query statement as below

  var account = orgContext.accountSet.Where(acct => (acct.name == “Rajeev”)).First();

• There were no ‘Accounts’ with name=Rajeev and using of First() resulted “Sequence contains no elements” exception

Fix:-

• Replace the method First() with FirstOrDefault().
• The method FirstOrDefault() returns a null value, if there are no records that matches to the filtering criteria
• Now my LINQ expression looks as below

  var account = orgContext.accountSet.Where(acct => (acct.name == “Rajeev”)). FirstOrDefault();
