I need help trying to work with a row accessed from a datatable using LINQ

Question

I am trying to get a single row from a data table using LINQ. It seems to getting the record but I am not able to work with it. Not sure what I am doing wrong. My LINQ query is below:

IEnumerable<DataRow> query = 
      from myRow in dataTable.AsEnumerable()
      where myRow.Field<int>("AM2MIN") <= Convert.ToInt32(minimumValue) &&
            myRow.Field<int>("AM2MAX") >= Convert.ToInt32(minimumValue)
      select myRow;

When I do the following to see if any records exist, it errors out.

if (query.Any())
{

}

InvalidCastException seems to be the consistent error.

Any help is much appreciated!

Answer 1

Looks like one of your fields does not contain integer value.

Verify Data Type of those columns. Also verify if Nulls are allowed for them. If data type is int , but nulls are allowed, then cast to nullable int: myRow.Field<int?>("AM2MIN") and verify if it has value.
