ASP.NET输出PNG图片时出现GDI+一般性错误的解决方法

复制代码 代码如下:

Response.Clear();
Response.ContentType = "image/PNG";
img.Save(Response.OutputStream, ChartFormat.Png);

复制代码 代码如下:

Response.ContentType = "image/jpeg";

复制代码 代码如下:

Response.ContentType = "image/PNG";
using (MemoryStream ms = new MemoryStream())
{
img.Save(ms, ChartFormat.Png);
Response.OutputStream.Write(ms.GetBuffer(), 0, (int)ms.Length);
}
