Course Introduction:Value types and references are both types in C# - value types Value type variables can be assigned directly. They are derived from the System.ValueType class. Value types contain data directly. When declaring an int type, the system allocates memory to store the value. Value type variables are stored on the stack. For example, int, char and float store numbers, letters and floating point numbers respectively. Reference type It refers to a memory location. Using multiple variables, reference types can refer to memory locations. If data in a memory location is changed by one of the variables, the other variable automatically reflects this change in value. Reference type variables are stored in the heap. An example built-in reference type is -objectdynamicstring
