Two favorite "new" C # syntax

C # Now compare the new syntax, I like it very much.

For example, a property can set a default value:

public string Name {get; set;} = "John";

Another is the stitching string.

In the past, it's not usually written like this:

String str = "ABC:" + a.tostring () + "," + b.tostring () + "," + c.tostring ();

But this:

String str = String.Format ("abc:{0},{1},{2}", a,b,c);

Much better than the first, but is not very intuitive, sometimes to the number of order to understand.

Well now, you can do this:

String str = $ "abc:{a},{b},{c}";

It's intuitive to write variables directly inside.

We can also combine with the "@" symbol. As we all know, the @ symbol, written in a variable, can define a variable with the same name as the system reserved word, such as

string @public;/hehe

In combination with a string, you can write an escape character directly in a string, such as

string path = @ "C:\temp\video\";
