Differences between string and string in C #

C #, string declaration, do you use string or string?
String? String? There is only one case-insensitive question. Which one do you prefer? Do you know the specific difference?
I am used to using string. The difference is that I recently found the authoritative basis, 'clr via C #'.
In fact, string is the name of the CLR type (also called keyword), while string is the keyword in C. The number of lines added by default during C # CompilationCode, You will understand the difference between string and string!
Using string = system. string; using sbyte = system. sbyte; using byte = system. byte; Using Short = system. int16; using ushort = system. uint16; using Int = system. int32; using uint = system. uint32 ;......
Right! Using string = system. String; C # compiler automatically converts string to sysem. String!
In CLR via C #, Jeffrey Richter recommends coding to use the default CLR type, that is, do not use string or string; do not use int to use int32! As for why, let's take a look at this book, very useful!
