I. Preparation Required software: Ildasm.exe: used to compile DLL and exe into il files. Ilasm.exe: used to compile the Il file back to DLL or EXE These two tools are installed with vs (vs2005 can handle 2003 of them, but not vice versa) Text

The. NET Framework Program can access the local code library through the static DLL entry point. The dllimport attribute is used to specify the DLL location that contains the implementation of an external method. The dllimport attribute is defined

Take notes. Do not omit things that you think are important or do not know before, and urge yourself to learn them. TIPS: The is and as operators both verify that the object is compatible with the specified type, and the strong conversion also

TIPS: Combination of optional and default parameters: static void Test(){ M(c: 5);}static void M(int a = 1, int b = 2, int c = 3){ //do sth} In this way, the default values can be used for the first two parameters. From the CLR

I have read some of my predecessors in the garden's articles on C # convolutional and inverter, And I have gained a lot. I will share my personal understanding, we hope to understand this concept in a simple way.   Covariant and inverter should be

When I first started learning C #, I heard that CLR has a special memory management mechanism for the string class: Sometimes, two string class objects are explicitly declared, however, they point to the same instance. As follows: String S1 = "hello

I recently looked for a job and interviewed several companies. I was very impressed by the interview questions from one of the companies. I have read similar questions in the blog park not long ago, but this is more complicated. The questions are as

Before learning about the principle of HTTP resumable upload, let's take a look at the HTTP protocol. HTTP is a simple TCP-based protocol, divided into two types: request and reply. A request protocol is a protocol used by a client (browser) to send

■Dynamic type C # from Version 1.0, You can dynamically access the information of an object even if you do not know its type. You only need to use reflection. Use reflection to access object member information Class{Public readonly

Many people on the internet asked the location where the settings file was stored. I read some articles and didn't give a clear answer. So let's track where the settings file is stored together, whether encryption protection exists. Settings is the

So far, multi-core computers with multiple kernels have not been widely used. Although many multi-core computer systems are used in the world of high-end servers in the high-end field, single-core or dual-core systems are still used in the low-end

Visual C # resource file programming-create a resource file A resource file is a file that stores resources. Resource files have their own unique advantages in programming. They are independent from source programs, so that resource files can be

We have explained the implicit type to the reader above. Next we will continue to discuss another new feature of C #3.0: anonymous type.20.2.1 introduce the anonymous type In many cases, we need an object that can temporarily store a batch of

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
