In C# equality is indicated with a double == operator.[^]

if (DataReader.GetInt32["trials_num"] == 0)

See Expressions (C# Programming Guide)[^] and check the difference between = and ==.

You can use:

C#
if (Convert.ToInt32(DataReader["trials_num"]) == 0)

Convert class is rarely needed, never performant, and in this case the GetInt32 method of DataReader class is the way that should be used.
