GDI +中出现一般错误 [英] A Generic error occured in GDI+

问题描述

嗨朋友们，



这是我的代码。

Hi friends,

This is My code.

sExtension = Path.GetExtension(Bigimg.FileName);
sFileName = Bigimg.FileName.Replace(Bigimg.FileName.ToString(), news.NewsId.ToString()) + sExtension;                        
string sPath1 = ConfigurationManager.AppSettings["BlockImagePath"].ToString() + sFileName;
if (!File.Exists(sPath1))
   File.Delete(sPath1);

Bigimg.PostedFile.SaveAs(sPath1);
System.Drawing.Image img = System.Drawing.Image.FromFile(sPath1);
img.Save(@sPath1, System.Drawing.Imaging.ImageFormat.Jpeg);

我使用上面的代码将图像格式转换为JPEG。


最后一行
， img.save 抛出异常GDI +中出现一般错误



请帮我解决这个问题。





谢谢。

I using the above code to convert image format to JPEG.

in last line, img.save thrown exception "A Generic error occured in GDI+"

Please help me to resolve this.


Thanks.

推荐答案

我在这里遇到一些困难，也许你可以解释一下：



1）你在这里使用一个字符串变量来替换另一个字符串。可以更容易地实现相同的结果

I'm seeing some difficulties here, maybe you can explain them:

1) You're using a string variable here to replace itself with another string. The same result could be achieved much easier

sFileName = Bigimg.FileName.Replace(Bigimg.FileName.ToString(), news.NewsId.ToString()) + sExtension;

//

sFileName = news.NewsId.ToString() + sExtension;

2）名为BlockImagePath的东西应该是一个字符串。所以不需要ToString（）它。

并使用 Path.Combine [ ^ ]可以帮助路径创建健壮性。

2) Something called "BlockImagePath" should be a string already. So no need to ToString() it.
And using Path.Combine[^] can help path creation robustness.

string sPath1 = Path.Combine(
    ConfigurationManager.AppSettings["BlockImagePath"],
    sFileName
);

3）删除不存在的内容？

3) Delete something that isn't there?

if (!File.Exists(sPath1))
   File.Delete(sPath1);

我想你没有！就想要那个。



4）你将图像保存到磁盘，再次读取，然后重新写入。

我认为你应该提供对 PostedFile 的数据类型的一些见解。

I suppose that you wanted that without the "!".

4) And the you're saving an image to disk, read it again, and re-write it another time.
I think you should provide some insight in the data type of PostedFile.

I将转换后的图像保存为另一个名称。现在它工作正常。



System.Drawing.Image img = System.Drawing.Image.FromFile（@sPath）;

sPath1 = ConfigurationManager.AppSettings [BlockImagePath]。ToString（）;

replacementname = Path.GetFileNameWithoutExtension（sPath）;

img.Save（ @ sPath1 + replacementname +1.jpg，System.Drawing.Imaging.ImageFormat.Jpeg）;



谢谢朋友们

I saved the converted image in another name.now it works fine.

System.Drawing.Image img = System.Drawing.Image.FromFile(@sPath);
sPath1 = ConfigurationManager.AppSettings["BlockImagePath"].ToString();
replacedname = Path.GetFileNameWithoutExtension(sPath);
img.Save(@sPath1 + replacedname + "1.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);

Thanks friends
