Cast function A cast function takes a number and converts it to the target integer type. Syntax: int<N>(x); uint<N>(x); int(x); // Alias of int<32>(x); uint(x); // Alias of uint<32>(x); Note: even though an int doesn't have a fixed size, we use the 32 bit cast...

Convert string to enum, but when enum type is only, var castTo = fieldInfo.PropertyType.GetType(); //returns a Type object, e.g. MyEnum var parsedEnum = (castTo) Enum.Parse(castTo, valueFromSql); The problem is that compiler wouldn't accept a variable that contains a Type object....
