如何C#自定义鼠标图片

private void panel1_MouseMove(object sender, MouseEventArgs e)
{
this.panel1.Cursor = new Cursor("chuizi1.ico");
}
private void pictureBox02_MouseUp(object sender, MouseEventArgs e)
{
this.panel1.Cursor = new Cursor("chuizi1.ico");
}
代码报错 显示图片已损坏

Answer 1

图片格式不正确的

Windows鼠标图像格式是ani和cur

虽然网上说ico和cur格式一样，不过我的不行 ，亲= =！！

这是帮助文档的实例
// Display a wait cursor while the TreeNodes are being created.
Cursor.Current = new Cursor("MyWait.cur");

Cursor 类不支持动画光标（.ani 文件）。

所以用的话最好转化下格式 然后在扔进Cursor里

hi,项目中也用到了这个,你可以尝试这个方式读取:
internal class BitmapCursor : SafeHandle {
public override bool IsInvalid
{
get
{
return handle == (IntPtr)(-1);
}
}

public static Cursor CreateBmpCursor(Bitmap cursorBitmap)
{

var c = new BitmapCursor(cursorBitmap);
return CursorInteropHelper.Create(c); }

protected BitmapCursor(Bitmap cursorBitmap)
: base((IntPtr)(-1), true)
{
handle = cursorBitmap.GetHicon();
}

protected override bool ReleaseHandle()
{
bool result = DestroyIcon(handle);

handle = (IntPtr)(-1);
return result; }
[DllImport("user32.dll")] public static extern bool DestroyIcon(IntPtr hIcon);
public static Cursor CreateCrossCursor()
{
const int w = 25;
const int h = 25;

var bmp = new Bitmap(w, h);
string imgPath = ""; // Your Absolute ImagePath
if (HelperMethods.DevelopMode())
{
System.Windows.Forms.MessageBox.Show(imgPath);
}
if (System.IO.File.Exists(imgPath))
{
bmp = new Bitmap(imgPath);
}
else
{
//系统图标
Graphics g = Graphics.FromImage(bmp);
g.SmoothingMode = SmoothingMode.Default;
g.InterpolationMode = InterpolationMode.High;

var pen = new Pen(Brushes.Black, 2);
g.DrawLine(pen, new Point(12, 0), new Point(12, 8)); // vertical line
g.DrawLine(pen, new Point(12, 17), new Point(12, 25)); // vertical line
g.DrawLine(pen, new Point(0, 12), new Point(8, 12)); // horizontal line
g.DrawLine(pen, new Point(16, 12), new Point(24, 12)); // horizontal line
g.DrawLine(pen, new Point(12, 12), new Point(12, 13)); // Middle dot

g.Flush();
g.Dispose();
pen.Dispose();
}

var c = CreateBmpCursor(bmp);
bmp.Dispose();
return c;
}
}

Answer 3

-“控制面板”---“鼠标”---在“鼠标属性”里找到“指针”---“自定义”里点一下你要改的鼠标样子---在点“浏览”找到电脑已经有的跟换鼠标的图片---按“确定”就完成了

Answer 4

你图片地址呢？

图片在 bin 的 begu里
