C#winForm自定義鼠標樣式的兩種方法

1、以前試過在C#WinForm中自定義鼠標樣式,結果顯示出來的鼠標變成單色。后來百度了下，原來要用API來做。首先引入兩個命名空間usingSystem.Runtime.InteropServices;usingSystem.Reflection;C#winForm自定義鼠標樣式方法一導入APIDllImport("user32.dll")ublicstaticexternIntPtrLoadCursorFromFile(stringfileName);DllImport("user32.dll")ublicstaticexternIntPtrSetCur

2、sor(IntPtrcursorHandle);DllImport("user32.dll")ublicstaticexternuintDestroyCursor(IntPtrcursorHandle);接下來使用自己的鼠標樣式privatevoidForm1_Load(objectsender,EventArgse)CursormyCursor=newCursor(Cursor.Current.Handle);IntPtrcolorCursorHandle=LoadCursorFromFile("my.cur");/鼠標圖標路徑myCursor.Get

3、Type().InvokeMember("handle",BindingFlags.Public|BindingFlags.NonPublic|BindingFlags.Instance|BindingFlags.SetField,null,myCursor,newobjectcolorCursorHandle);this.Cursor=myCursor;C#winForm自定義鼠標樣式方法之二現在介紹另一種不用API方式的，鼠標樣式只需要一張背景透明的圖片就行了，png或gif格式的寫個方法publicvoidSetCursor(Bitmapcursor,Pointhot

4、Point)inthotX=hotPoint.X;inthotY=hotPoint.Y;BitmapmyNewCursor=newBitmap(cursor.Width*2-hotX,cursor.Height*2-hotY);Graphicsg=Graphics.FromImage(myNewCursor);g.Clear(Color.FromArgb(0,0,0,0);cursor.Width,g.DrawImage(cursor,cursor.Width-hotX,cursor.Height-hotY,cursor.Height);this.Cursor=newCursor(myNewC

5、ursor.GetHicon();g.Dispose();myNewCursor.Dispose();在你想要改變鼠標樣式的事件里頭使用這個方法就行了privatevoidForm1_Load(objectsender,EventArgse)Bitmapa=(Bitmap)Bitmap.FromFile("myCur.png");SetCursor(a,newPoint(0,0);/this.btnBack.FlatStyle=FlatStyle.Flat;/setthebuttonnoframe/this.btnBack.FlatAppearance.BorderSize
