SystemInvalidCastExceptionUnable to cast object of type SystemInt32 to type SystemInt64

This error occurs when the program tries to convert an integer value from one type to another, but the conversion is not possible due to a mismatch of data types. In this specific case, the program is trying to cast an integer value of type Int32 to a long integer value of type Int64, which is not possible because the two data types are different. To resolve this error, the program needs to use a suitable conversion method or modify the data type of the variable being used to match the data type of the value being cast.
