问 题

嗨所有

当我想从fileupload中保存图像时遇到问题。

我的代码是:



  string  filename = "  nopic.gif"; 


if (fileupload1.hasfile)
{


filename = fileupload1.filename;

位图bmp = new 位图(fileupload1.filecontent);
system.drawing.image img = bmp;

resizeimage.imageresize imgre = new resizeimage.imageresize();
img = imgre.resize(img, 85 113 );




// string directory = server .mappath(@"\\\ minmin \ teacherpic \\");
string directory = server.mappath(" ./ all_images / foroshgahimages /");
img.save(目录+文件名);

}




提示:此代码运行其他地方。在此位置我的网页内容updatepanel。

解决方案

"行中的问题:img.save(目录+文件名);"



在这种情况下,我怀疑问题是上面的一行:

  string  directory = server.mappath("  ./ all_images / foroshgahimages /"); 
可能返回无效路径,或者未正确设置目录写入权限。在保存文件之前检查目录值。



查看您是否获得了有用的信息。异常和内部异常通过将其封闭在try / catch中 - 这可能有助于隔离它。

我发现我的错误

错误是这样的:

位图bmp =  new 位图(fileupload1.filecontent); 
system.drawing.image img = bmp;

resizeimage.imageresize imgre = new resizeimage.imageresize();
img = imgre.resize(img, 85 113 );


现在如何调整我的图像大小
