Can I refer to a bool or int?

Question

I'd like to create a reference to value types such as int or bool. It's something like this: int i =5; int j = ref i; j = 6; // I hope the value of i be 6 instead of 5. How can I do this?

maybe you can create your class with need you value. It's something like this: class refInt { public int i; /* other value */ public refInt(int j) { i = j; } } class Class1 { static void Main(string[] args) { refInt i = new refInt(5); refInt j = i; j.i = 6; Console.WriteLine(This is i = {0}i.i); } }

Yes bool or int may be passed by reference when calling a method. But if I am not calling a method and I want to refer to the variable how can I do this? Somebody will tell me 'why not change the value directly'. I agree that in most cases the value should be changed directly. But there are still cases that you have to remember which variable to change and change it later such as the code shown in C.

Hi C# has explicit syntax for pointers and references (same as C++) when using unsafe code blocks. Hope this helps.

C# doesn't have explicit syntax for pointers. However I believe passing variables with the ref keyword does the same thing as passing a pointer as a parameter when calling a method.

In C or C++ you can write like this: int a b c d; int *i; if( something ) i = &a; else if ( something else ) i = &b; else if ( something else else) i = &d; else i= &e; *i = ( something ); I want to do the similar thing in C#.

I don't think I understand your problem much if you want to assign the value of j to i it's as simple as this: i = j; if you want to assign it in case of something else just use if or case... you should be more specific....
