Summary of differences between out and ref:1. Both are passed by reference.2. Both are passed by address and will change the value of the original parameter after use.3. The property is not a variable and therefore cannot be passed as an out or ref

A Summary (The content of this article is mostly from the network, by my collation, only for the study reference, unavoidably understand the mistake, welcome criticism correct) In C #, the parameters of a method are passed in four different

I. parameter types in C # methodsThere are 4 types of parameters, sometimes it is difficult to remember their different characteristics, to make a summary, making it easier to compare and contrast.Ii. parameters in the C # method1. Value

The transfer of parameters is generally divided into two types: one is "value passing" i.e. a copy of the passed argument, and since it is a copy, any action on the parameter in the function will not be reflected in the original argument. The other

Three advanced parameters ref out and params for C #In our study of C # Foundation, we will learn the C # three advanced parameters, respectively, is out. Ref and params, here we are to explain separately, here we do not do a specific explanation, I

C # In the out and ref2007-09-19 A Brief Introduction on msdn:The out keyword causes the parameter to be passed through reference. This is similar to the ref keyword, except that the ref requires that the variables must be initialized

If we need to return multiple results for a method during design, we usually use the ref or out parameter. At the same time, we still use generic tuples to return multiple irrelevant values. Let's take a look at the following code, first define a

RefKeywords are often used in C #, but they have never been carefully considered. I often write code, but I haven't figured out the basics yet. I used to think that using ref is a reference. If you change the parameter value in this method, the
