C# Razor asp.net Cannot invoke non-delegate type

Question

I'm running into an error with my razor template that says: Error compiling Razor Template: Cannot invoke a non-delegate type (check logs for more details)

I've tried declaring the variables with @ and without @ in front both methods give the same error.

The looping portion at the bottom works fine it's just the singular non-looping dates at the top i'm having trouble with.

@{
var FDate1 = @AME.GridF18.FDate1("SubmissionID='" + TknParams.SubmissionID + "'");
var FDate2 = @AME.GridF18.FDate2("SubmissionID='" + TknParams.SubmissionID + "'");
var FDate3 = @AME.GridF18.FDate3("SubmissionID='" + TknParams.SubmissionID + "'");
var FDate4 = @AME.GridF18.FDate4("SubmissionID='" + TknParams.SubmissionID + "'");
var FDate5 = @AME.GridF18.FDate5("SubmissionID='" + TknParams.SubmissionID + "'");
var FDate6 = @AME.GridF18.FDate6("SubmissionID='" + TknParams.SubmissionID + "'");
var FDate7 = @AME.GridF18.FDate7("SubmissionID='" + TknParams.SubmissionID + "'");
}

Error compiling Razor Template: Cannot invoke a non-delegate type

Because of this statement

@foreach (var row in AME.GridF18("SubmissionID='" + TknParams.SubmissionID + "'")) {

Here the GridF18 is treated as delegate by the compiler which it is expecting to return an IEnumerable.

It looks like you are trying to loop through a list of dates. You need to create a list then add those dates to the list and use that list in your loop as collection source
