unmanaged

Let's face it. The world is not perfect. Almost a few companies are developing programs entirely with managed code, and there are still a lot of legacy unmanaged code that you need to work with. How do you integrate managed and unmanaged projects?

I've talked about how to generate a C # static reference declaration (C # and unmanaged-first experience) from a C function declaration with a simple lookup substitution, because it's just a simple explanation, so it's all based on basic type

What is C # managed code?Managed code is actually the intermediate language (IL) code Managed. After the code is written, the compiler compiles the code into the intermediate language (IL) instead of the machine code that runs directly on your

Objects in C # are classified into value and reference types. The biggest difference between them is the data storage method and storage location. in Windows, the virtual addressing system is used to manage the data storage generated when the

Recommendation 50: Treat managed and unmanaged resources differently in Dispose modeThe virtual method of the real resource release code is a bool parameter with this parameter because we want to differentiate between managed and unmanaged resources

Unlike office and home Ethernet, which has long been known, industrial Ethernet requires more professional knowledge and practical experience. If you are installing or using an industrial Ethernet, the five points about wiring, signal quality,

I studied the 5-day garbage collector, read Wang Yonggang's article, two articles on Code project and msdn, and finally understood a little bit. In the. NET programming environment, system resources are divided into managed resources and unmanaged

Marshal. Copy cannot copy data from the offset of the unmanaged pointer. You need to recalculate the value of the unmanaged pointer. ////// Read data////// Data/// Start address/// Number///Public int read (ref byte [] bytdata, int lngaddr, int

In A. NET programming environment, the system's resources are divided into managed and unmanaged resources.Managed Resources:NET platform, the CLR provides programmers with a good memory management mechanism that allows programmers to write code

C and C ++ have a lot of good class libraries. NET, it is unwise and unrealistic to discard them completely and re-start them. Therefore, we often need to use the previously left-behind Unmanaged dll through Pinvoke. As for the use of unmanaged dll

For backward compatibility, C # and. NET can run legacy code in an unmanaged way. Unmanaged code means that it is not. NET runtime to control the code. Unmanaged code mainly includes: Platform invoke service (platforminvocation services), unsafe

  Why write this article? 1. If you want to inject a dll with a form, the C # Write interface is much easier than the C ++ interface;   2. You may want to use some. net functions, such as using. Net Remoting to control the injected dll from the
