The difference between a primitive type, a reference type, and a value type;1. Primitive type (primitive type): The data type directly supported by the compiler, and primitive types directly mapped to types that exist in the FCL.C # Lowercase is a primitive type, for example: string, uppercase is the FCL type, such as String, primitive types are directly mapped t
Basic conceptsValue type:A value type instance is typically assigned on the thread's stack (stack) and does not contain any pointers to the execution of the instance data because the variable itself contains its data instance. Its definition in MSDN is that value types directly contain their data, and instances of value types are either on the stack or inline in the structure.Value

Admittedly some friends will say "Web API is not used, it is for a certain situation ... You should construct an object ... "but, since there is such a usage, the solution to the problem that this article is addres

. NET, the data types that the compiler supports directly are called primitive types (primitive type). Primitive types and.

See the big God on the Internet a blog post on whether the Java language has a value type, which mentions that "Java has only reference types (reference type), but according to Java's official documentation, Java also has the difference between a value type and a reference type." Primitive types such as Int,boolean are value types. "Original address: http://yinwa

performance testing, we need to use the tools provided by the operating system to collect various types of resource monitoring data in the operating system, including CPU, memory, and hard disk usage data. If the tested program uses the network, you also need to collect network usage data. Only when the collected data is complete and sufficient can the performance test results be more accurate and performa
