We already know what hosting is.Code, Il, metadata,ProgramAnd so on. Now let's take a look at how the code we write runs on the DOTNET platform.When executing a method, the CLR detects all types of code referenced by the method. As a result, the CLR

ConstantIt is a symbol that will never be changed after definition. Its value must be determined during compilation. After compilation, the compiler saves the constant value inProgramIn the set metadata, defining constants will lead to metadata

The string object may contain some sensitive data, such as the user password.CodeThe code can scan the address space of the Process, find the string containing sensitive data, and use the data in an unauthorized way, even if the string object only

CLR can arrange fields of the type in any way it chooses. It can indicate whether to maintain the sequence specified by the developer or re-arrange the fields as needed, in order to improve performance. Apply on the definition class or

Three implementation methods are listed in the order of performance: (1) Forced type conversion:This is the simplest and most efficient method, because the compiler generates intermediate language instructions to execute the conversion without

After the design, the reference to the broadband connection only generates the interface of the specific idowork object, which reduces many coupling. Next we will implement this project, create the project adslservice, and add a class called ADSL,

I personally think that we must first learn a language that runs on CLR before learning CLR, to be familiar with it. It is boring for most people to learn basic theories before they get started, many won't stick to it. Now we want to follow Jeffrey

Now let's take a look at how CLR works. Assume there are two classes defined as follows: Internal Class Employee { Public Int32Getyearsemployed () { //... } Public Virtual StringGenprogressreport () { //... }
