C# "var" argument in method without using generics (templates) -

i have set of simple function identical except passed data types. data types basic types.

i tried use "var" expected compiler not know how handle functions internal types.

do need use generics (templates) here?

or there other built in featured c# not aware of?

thanks in advance help!

protected bool checkpropertychanged(ref bool attribute, bool newvalue) {     bool propertychanged = false;     if (attribute != newvalue)     {         propertychanged = true;         attribute = newvalue;     }     return propertychanged; }  protected bool checkpropertychanged(ref string attribute, string newvalue) {     bool propertychanged = false;     if (attribute != newvalue)     {         propertychanged = true;         attribute = newvalue;     }     return propertychanged; } 

i used solution below found attribute not being modified when using generics, regardless of how called method. reverted original code of having separate methods , revisit... didn't take time investigate... possible i'm doing stupid here.

static bool checkpropertychanged<t>(ref t attribute, t newvalue) {     if (!attribute.equals(newvalue))     {         attribute = newvalue;         return true;     }     return false; } 

yes generics can 1 solution, can try somehting like

static bool checkpropertychanged<t>(ref t attribute, t newvalue) {     if (!attribute.equals(newvalue))     {         attribute = newvalue;         return true;     }     return false; } 

and call:

checkpropertychanged<bool>(ref a, b) 

or

checkpropertychanged<string>(ref a, b) 

or whatever type want. make sure .equals returns expect depending of types want compare.

i think generics clean solution. there reason why want without generics?
