What's the Key Difference Between Reference and Value Types in C#?

In -depth understanding of the reference type and value type in C#

The difference between the reference type and value type in C#, a common misunderstanding is that the value type only includes basic types such as int, book, and flow, while reference types include commission and interface. However, this explanation is not completely accurate.

To be precise, in C#, the value type is a self -contained unit that stores data directly in the variables. Any changes made by the value type variable will only affect its own data, and will not affect other variables of the same type. The main examples include integers, Boolean values ​​and floating points.

On the other hand, the reference type storage references the actual data, not the storage data itself. This means that multiple variables of the same reference type point to the same position in memory, thereby realizing data sharing. Modifying the data through a reference variable will affect all other variables that reference the same data. Common examples of reference type include objects, array and string.

Understanding this difference is essential to effectively use C#. The reference type allows the use of complex data structures, where the object is referenced by other objects in layers. But be careful, because modifying the data may accidentally affect the irrelevant part of the program.
