specification and standard Query Operators overview.
as a rule for writing LINQ queries, it is recommended that you use the query syntax as much as possible, and only if necessary to use method syntax. query expressions are often easier to read than equivalent expressions written in method syntax.
countmax, has no equivalent query expression clause and must therefore be express Ed as a method call. " > Some query operations, such as Count or Max, do not have an equivalent

How to: declare and use read/write attributes (C # programming guide)Attributes can provide convenience for public data members, without the risk of being unprotected, uncontrolled, and unauthenticated access to object data. This is achieved through the "accessor": The accessor is a special method

source files. when compiling a multi-file C # program, you can process all the source files together, and the source files can be arbitrarily referenced to each other.Conceptually, it is like all source files are concentrated into a large file before processing.in C #, it is never necessary to use forward declarations, because the order of declarations is insignificant (except for very few exceptions).
at this point, the void* pointer type is very good.In view of this, all compilers provide a default convenience: that is, any type of pointer can be converted to the void* type, the compiler will not errorLike whatchar* PA = a;memset (pa,1,1);The compiler does not error, suggesting that you have a wrong pointer to the PA. Instead, it is silently converted to the void* type.This section is primarily about pointers, and will continue to explain the pointers slowly. The pointer changes very much,

Variables (pointers, arrays) should be initialized immediately after they are created to prevent variables that are not initialized are used as rvalue values. Recommendation 3. Beware of variable initial values, default errors, or insufficient precision.recommendation 4. Beware of errors in data type conversions.

C # multithreading User Guide ~~
I did not dare to share the articles I found on the Internet. I sent them for research !!Net provides many multi-threaded programming tools, probably because there are too many tools, so there is always a headache to grasp. Here I will talk about some of my multi-threaded programming experiences, hoping to help you.
You do not need to pass parameters or return parameters.
