The replace function in JavaScript and the replace method in C #

This is a problem that has never been noticed. The point is that replace in C # is a global replacement character (string), while in Javascript, it is only replaced with the first matched character.Code, JavaScript is as follows:

 
VaRSource='Abc123abc456abc';
VaRDesc=Source. Replace ('ABC','');
Alert (DESC );
 

The result is 123abc456abc.

The code in C # is as follows:

String source = "abc123abc456abc"; string DESC = source. Replace ("ABC", ""); console. Write (DESC );
 

Result: 123456

The corresponding JavaScript function should be written as follows:

 
VaRSource='Abc123abc456abc';
VaRDesc=Source. Replace (/ABC/G,'');
 

In this case, the implementation of C # is hard to understand. So we decompiled the string.

It seems that this should introduce the. NET kernel function. Then use msil to decompile mscorlib. dll and find the replace implementation:

We can see that it is internally called the pencil class library. Of course, this class library has been encapsulated internally and we cannot know the implementation.

Here we leave a todo.
