C＃中：如何加载光标从资源文件？ [英] C#: How to load Cursor from Resource file?

问题描述

我已经导入的文件x.ani到资源文件Resources.resx。现在试图加载使用ResourceManager.GetObject该文件（aero_busy.ani）

I have imported a file "x.ani" into Resource file Resources.resx. Now trying to load that file using ResourceManager.GetObject("aero_busy.ani")

Cursor.Current = (Cursor)ResourcesX.GetObject("aero_busy.ani");

但没有奏效。（当然）:)

but it didn't work .. (certainly) :)

使用资源的对象我怎样才能改变当前光标？

How can I change the current Cursor using resource object?

推荐答案

我还没有发现任何高于倾销到一个临时文件，并使用Win32负载光标从文件的方法更好的方法。该黑客是这样的（我删除的样板code一大块为清晰起见，在一个临时文件从流写入数据）。此外，所有异常处理等已被删除。

I haven't found any better way than dumping to a temp file and use the Win32 load cursor from file method. The hack goes something like this (I removed a big chunk of boilerplate code for clarity, in which a temp file is written with the data from the stream). Also, all exception handling etc. was removed.

[DllImport("User32.dll", CharSet = CharSet.Ansi, BestFitMapping = false, ThrowOnUnmappableChar = true)]
private static extern IntPtr LoadCursorFromFile(String str);

public static Cursor LoadCursorFromResource(string resourceName)
{         
     Stream cursorStream = Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceName);        

     // Write a temp file here with the data in cursorStream

     Cursor result = new Cursor(LoadCursorFromFile(tempFile));
     File.Delete(tempFile);

     return result.
}

您会用这个作为（加载嵌入的资源时记得命名空间）。

You would use this as (remember namespaces when loading embedded resources).

Cursors.Current = LoadCursorFromResource("My.Namespace.Filename");
