Recently, I used csom to parse the Web Part attributes and found that reading the XML with namespace is really a little disgusting. To put it bluntly, I am too lazy to go into details. I think it would be nice to convert it into something similar to

20.1 implicit type Added a variable declaration VaR in C #3.0. This declaration and javasCallback VaR is similar, but it is also different. The same is that it can use VaR to declare any type of local variables. The difference is that it is only

The anonymous method is introduced in C #2.0, which can be replaced by "inline" code when a delegate is expected. Although the anonymous method provides a lot of expression capabilities in functional programming languages, the syntax of the
