How can I change the mouse cursor image?
提问by RV.
I need to change the cursor image. Whenever the mouse is over my form I need to load my own image from a local path. I am using version 1.1 of the .NET framwork.
我需要更改光标图像。每当鼠标悬停在我的表单上时，我都需要从本地路径加载我自己的图像。我正在使用 .NET 框架的 1.1 版。
Here is what I have tried:
这是我尝试过的：
Cursor = new Cursor(GetType(), Application.StartupPath+ "\windowfi.cur");
But this throws an exception:
但这会引发异常：
Value cannot be null.
Parameter name: dataStream
值不能为空。
参数名称：数据流

Cursor class has a constructor that takes in cur file path as a parameter. Use that. Like this:
Cursor 类有一个构造函数，它接受 cur 文件路径作为参数。用那个。像这样：
this.Cursor = new Cursor("<your_cur_file_path");

This should probably work:
这应该可以工作：
Cursor.Current = new Cursor(GetType(), Application.StartupPath+ @"\windowfi.cur");
or
或者
Cursor.Current = new Cursor(GetType(), Application.StartupPath+ "\windowfi.cur");
Note the use of @ string literal and the \ escape character above to be able to use the backslash character correctly in the path to the cursor's icon. As well as the Currentproperty of the Cursor class.
请注意上面@字符串文字和\转义字符的使用，以便能够在光标图标的路径中正确使用反斜杠字符。以及Cursor 类的Current属性。

It looks like you're using the wrong overload for the cursor constructor. If you want to use a file path, use the constructor overload that just takes a string. You are using the overload that takes a type and a string. That overload gets an embedded resource.
看起来您对游标构造函数使用了错误的重载。如果要使用文件路径，请使用仅接受 string 的构造函数重载。您正在使用采用类型和字符串的重载。那个重载得到一个嵌入的资源。
