Hi,

In C#, parameters can be passed either by value or by reference. Passing parameters by reference allows function members (methods, properties, indexers, operators, and constructors) to change the value of the parameters and have that change persist. To pass a parameter by reference, use the ref or out keyword. For simplicity, only the ref keyword is used in the examples of this topic. For information on the difference between ref and out, see http://msdn.microsoft.com/en-us/library/14akc2c7%28VS.71%29.aspx, http://msdn.microsoft.com/en-us/library/t3c3bfhx%28VS.71%29.aspx, and http://msdn.microsoft.com/en-us/library/szasx730%28VS.71%29.aspx.

Hi

In Visual C# 3.0, variables that are declared at method scope can have an implicit type var. An implicitly typed local variable is strongly typed just as if you had declared the type yourself, but the compiler determines the type. The following two declarations of i are functionally equivalent:
