保存图像时发生GDI +的一般错误图片

我读了同一个问题的答案，并做了所要求的任何事情。我也给当前用户的文件夹写入权限，如前面的答案之一所述，但仍然出现此错误。所以请任何人都能为我提供具体的答案。这是我的代码保存图像时发生GDI +的一般错误图片

protected void Page_Load(object sender, EventArgs e) 
{ 
    //get all the files in a directory 
    string[] files = Directory.GetFiles(@"D:\Naved\BasicDotNet\Images"); 

    //combine them into one image 
    System.Drawing.Bitmap stitchedImage = Combine(files); 

    //save the new image 
    stitchedImage.Save(@"D:\Naved\BasicDotNet\Images", System.Drawing.Imaging.ImageFormat.Jpeg);//Error:-A generic error occurred in GDI+ 

} 
public static System.Drawing.Bitmap Combine(string[] files) 
{ 
    //read all images into memory 
    List<System.Drawing.Bitmap> images = new List<System.Drawing.Bitmap>(); 
    System.Drawing.Bitmap finalImage = null; 

    try 
    { 
     int width = 0; 
     int height = 0; 

     foreach (string image in files) 
     { 
      //create a Bitmap from the file and add it to the list 
      System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(image); 

      //update the size of the final bitmap 
      width += bitmap.Width; 
      height = bitmap.Height > height ? bitmap.Height : height; 

      images.Add(bitmap); 
     } 

     //create a bitmap to hold the combined image 
     finalImage = new System.Drawing.Bitmap(width, height); 

     //get a graphics object from the image so we can draw on it 
     using (System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(finalImage)) 
     { 
      //set background color 
      g.Clear(System.Drawing.Color.Black); 

      //go through each image and draw it on the final image 
      int offset = 0; 
      foreach (System.Drawing.Bitmap image in images) 
      { 
       g.DrawImage(image, 
        new System.Drawing.Rectangle(offset, 0, image.Width, image.Height)); 
       offset += image.Width; 
      } 
     } 

     return finalImage; 
    } 
    catch (Exception ex) 
    { 
     if (finalImage != null) 
      finalImage.Dispose(); 

     throw ex; 
    } 
    finally 
    { 
     //clean up memory 
     foreach (System.Drawing.Bitmap image in images) 
     { 
      image.Dispose(); 
     } 
    } 
} 
}

有多大图片？ –

您正在从'@“D：\ Naved \ BasicDotNet \ Images”加载图片，因此必须是一个目录 - 但是您可以['stitchedImage.Save（@“D：\ Naved \ BasicDotNet \ Images”， System.Drawing.Imaging.ImageFormat.Jpeg）;']（https://msdn.microsoft.com/en-us/library/9t4syfhh%28v=vs.110%29.aspx） - 尝试覆盖pre-与*文件*具有相同名称的现有目录。尝试一个不同的名字。 Image.Save的'string'参数是要保存的文件，而不是要保存的目录。 – dbc

尝试

stitchedImage.Save(@"D:\Naved\BasicDotNet\Images\stitchedImage.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);

，而不是

stitchedImage.Save(@"D:\Naved\BasicDotNet\Images", System.Drawing.Imaging.ImageFormat.Jpeg);

的第一个参数Image.Save (String, ImageFormat)是文件名保存到其中，而不是目录要保存。先前您已完成

string[] files = Directory.GetFiles(@"D:\Naved\BasicDotNet\Images");

因此@"D:\Naved\BasicDotNet\Images"必须是目录，而不是文件。

（顺便说一句，我建议拼接图像保存到不同的目录，否则，每次你运行你的代码，你会与以前的内容缝合在一起之前的针。）

Thankx其工作 – Navy

stitchedImage.Save(@"D:\Naved\BasicDotNet\Images", System.Drawing.Imaging.ImageFormat.Jpeg); - you need to specify the file name here. I.e edit it to something like this:  `stitchedImage.Save(@"D:\Naved\BasicDotNet\Images\myjpeg.Jpeg", System.Drawing.Imaging.ImageFormat.Jpeg)`
