Reflection provides objects of type System.Type that describe assemblies, modules and types. It allows you to create an instance of a type, and bind it to an existing object, or get the type from an existing object and invoke its methods or access its fields and properties.
You can use GetType method to obtain the type of a variable.
// Using GetType to obtain type information:
int number = 60;
string str = "Expression Trees vs Reflection";
double doubleVal = 12.5;
Type numType = number.GetType();
Type strType = str.GetType();
Type doubleType = doubleVal.GetType();
