如何使用WinAPI索引中的.dll文件？ [英] How to use .dll files from WinAPI Index?
问题描述
我的目标是导入任何.dll文件以使用任何Windows API。
有Windows API索引，我选择任何.dll来包装使用。
http ：//msdn.microsoft.com/en-us/library/ff818516（v = vs.85）.aspx [ ^ ]
我选择了下一个.dll，我怎么包装才能使用？我不能，因为没有关于这样一个目标的信息，换句话说，Windows API参考不是为了这样的目标。
http://msdn.microsoft.com/en-us/library/ms535564（v = vs.85 ）.aspx [ ^ ]
有.NET Framework类库，它显示了我在C＃程序中使用它们时需要知道的一切。我需要关于WinAPI的相同内容。
http ：//msdn.microsoft.com/en-us/library/gg145045（v = vs.100）.aspx [ ^ ]
下一个是我需要什么，但它是某些类的例外。
http://msdn.microsoft.com/en-us/library/ms534039%28VS.85%29.aspx [ ^ ]
我有大纲的工作代码，但我从最后一个只有600个函数的链接中得到它，但我想对从Windows API索引中选择的任何.dll做同样的事情。
我认为Windows API索引引用是专门用于C ++的，而不是C＃。
My goal is to import any .dll file to use any Windows API.
There is Windows API Index where i choose any .dll to wrap to use.
http://msdn.microsoft.com/en-us/library/ff818516(v=vs.85).aspx[^]
I chose the next .dll, how can i wrap it to use? I can't because there is no information for such a goal, in other words Windows API reference is not made for such a goal.
http://msdn.microsoft.com/en-us/library/ms535564(v=vs.85).aspx[^]
There is .NET Framework Class Library, it shows everything i need to know to use them in my C# program. I need the same thing about WinAPI.
http://msdn.microsoft.com/en-us/library/gg145045(v=vs.100).aspx[^]
The next one is what i need for, but it an exception for certain classes.
http://msdn.microsoft.com/en-us/library/ms534039%28VS.85%29.aspx[^]
I have the working code for Outline, but i got it from the last link where are just 600 functions, but i wanna do the same thing with any .dll i choose from Windows API Index.
I think Windows API Index reference is specialized for C++, not for C#.
推荐答案
确定所以你需要做的第一件事就是使用windows api函数（这是针对DLLUser32.dll）是添加对System.Runtime.InteropServices的引用
通过这样做：
ok so the first thing you need to do in order to use a windows api function(this is for the DLL "User32.dll") is to add a reference to the System.Runtime.InteropServices
by doing this:
using System.Runtime.InteropServices;
然后你像这样导入DLL（注意你在winform app的构造函数之前的空格中这样做）：
then you import the DLL like this(note you do this in the space right before the constructor for a winform app):
[DllImport("user32.dll")]
这里是一个如何从新导入的User32.dll导入LockWorkStation方法的示例（注意：你应该添加进程DLL导入语句下的代码行）：
here is an example of how to import the LockWorkStation method from the newly imported "User32.dll" (Note: you should add the proceeding line of code right under the DLL import statement):
public static extern void LockWorkStation();
现在这个方法不接受任何参数，所以你这样称呼：
now this method doesn't take any arguments so you call it like this:
LockWorkStation();
这会锁定你的电脑所以我会把它放在一个按钮事件方法或什么东西
这个是一个非常简单的使用windows api和一个非常容易操作的操作。
C＃可以访问windows api它比C ++稍微难一点。
i希望这个得到你开始并帮助，

this will lock your computer so i would put this in a button event method or something
this is a very simple use of the windows api and a very easy to do operation.
C# can access the windows api its just a little harder than C++.
i hope this gets you started and helps,

这是你已经发布过两次的完全相同的问题，答案仍然是一样的。您使用P / Invoke从.NET应用程序访问Windows API函数;没有其他文件。选择您要使用的功能，并在P / Invoke网站上查找。如果没有引用它，那么你需要自己计算出调用顺序。
This is exactly the same question that you have already posted twice, and the answer is still the same. You use P/Invoke to access Windows API functions from .NET applications; there is no other documentation. Choose the function you wish to use and look it up on the P/Invoke website. If there is no reference to it then you will need to work out the calling sequence for yourself.
解决了！
问题：如何使用.dll文件？
1.转到WinAPI索引。
http://msdn.microsoft.com/en-us/library/ff818516(v = vs.85）.aspx [ ^ ]
2.选择任何.dll文件。
http://msdn.microsoft.com/en-us/library/ms646294(v = vs.85）.aspx [ ^ ]
3.使用平台调用（C＃，Windows Forms，.Net Framework 4.0，Visual Studio 2010）。
Solved!
Question: How to use .dll files?
1. Go to WinAPI Index.
http://msdn.microsoft.com/en-us/library/ff818516(v=vs.85).aspx[^]
2. Choose any .dll file.
http://msdn.microsoft.com/en-us/library/ms646294(v=vs.85).aspx[^]
3. Use Platform Invoke (C#, Windows Forms, .Net Framework 4.0, Visual Studio 2010).
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Drawing.Drawing2D;
using System.Runtime.InteropServices;
using System.Reflection;
namespace _123
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
Method();
}
[DllImportAttribute(@"User32.dll")]
static extern void GetFocus();
private void Method()
{
GetFocus();
}
}
}
问题：如何以相同的方式使用GDI + Flat API ？
答：不可能以同样的方式使用任何GDI + Flat API。
1.例如，选择一个简单的GDI + API：
http://msdn.microsoft.com/en-us/ library / ms535564（v = vs.85）.aspx [ ^ ]
2.你不能使用它！
问题：为什么？
答案：因为：
Question: How to use GDI+ Flat API in the same way?
Answer: It is impossible to use any of GDI+ Flat APIs in the same way.
1. For example, choose a simple GDI+ API:
http://msdn.microsoft.com/en-us/library/ms535564(v=vs.85).aspx[^]
2. You can not use it!
Question: Why?
Answer: Because of:
Microsoft产品支持服务不会为调用的代码提供支持平面API直接
Microsoft Product Support Services will not provide support for code that calls the flat API directly
http： //msdn.microsoft.com/en-us/library/ms534039%28VS.85%29.aspx [ ^ ]
问题：可以使用任何Windows API索引的Windows API直接API？
答：不可能直接使用所有这些API，你只能直接使用.dll文件。因此，您应该使用C ++为这些API生成.dll文件，以便通过使用Platform Invoke在C＃中使用它们。
http://msdn.microsoft.com/en-us/library/ms534039%28VS.85%29.aspx[^]
Question: Is it possible to use any API of Windows API from Windows API Index directly?
Answer: It is impossible to use all of them directly, you only can use .dll files directly. As a result, you should use C++ to make .dll files for those APIs to use them in C# by using Platform Invoke.
