The road will never execute since const variables has to be assigned at enough time of compile time itself.
In a perform, it remains a persistent variable, so you may As an example rely the amount of moments a purpose has actually been identified as.
While a constant value are unable to alter. It's got its worth constant in full in the code. Such as, in case you set the constant variable like "const int a=5", then this benefit for "a" is going to be constant in whole of the program.
Use const when the worth is complete constant that gained’t alter more than some time. Such as Amount of times in per week is 7. This is often constant. and when unsure use static readonly to stay away from the dll versioning difficulty.
Naturally that makes sense for the reason that that static approach would not know which occasion of The category the get these from Except it ended up told, considering that It is far from Section of an instance alone)

If you want a field for being a assets of a type, and never a residence of an instance of that form, use static.
