Answer 1

我发现是我画图时使用了  bmp=new Bitmap(this.pictureBox1.Width,this.pictureBox1.Height);
this.pictureBox1.Image=(Image)bmp;
g=Graphics.FromImage(this.pictureBox1.Image);
而产生的，我去掉后就不会产生这个异常了，但我也画不了图了，怎么解决啊？？？

Answer 2

bmp=new   Bitmap(this.pictureBox1.Width,this.pictureBox1.Height); 
this.pictureBox1.Image=(Image)bmp; 
g=Graphics.FromImage(this.pictureBox1.Image); 
try changing to:
if( this.pictureBox1.Image == null )
{
  this.pictureBox1.Image = new Bitmap(this.pictureBox1.Width,this.pictureBox1.Height); 
}
g=Graphics.FromImage(this.pictureBox1.Image);
