Difference between static, readonly, and constant in C# (part 2)

readonly:

Declared using the readonly keyword.

Only the class level fields can be readonly. The local variables of methods cannot be readonly.

Readonly fields can be initialized at declaration or in the constructor. Therefore, readonly variables are used for the run-time constants.

Readonly variable cannot be modified at run-time. It can only be initialized or changed in the constructor.

Readonly members can be accessed using object, but not ClassName.ReadOnlyVariableName.
