我需要从 XML 文件中删除回车，但我得到的只是一个带有一个框的 XML 文件（\ r）。我是这样写的：

    string sourceFileName = textBox1.Text;

                     StreamReader sr = new StreamReader(sourceFileName);

                     String line;
                     String newLine = null;
                     // Read and display lines from the file until the end of 
                     // the file is reached.
                     while ((line = sr.ReadLine()) != null)
                     {

                         //Regex regex = new Regex(@"(\r\n|\r|\n)+");

                         newLine = line.Replace("\r\n", String.Empty);
//also tried line.Replace("\n", String.Empty).Replace("\r",String.Empty); , but no use

                         StreamWriter sw = new StreamWriter(@"C:\Users\manish\Desktop\output.xml");
                         sw.WriteLine(newLine);
                         sw.Close();
    }

这里可能有什么问题。

我想获取从库中挑选或最近点击的图像的名称 -

-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

我正在使用此代码:

-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeSavedPhotosAlbum])
    {
        AppDelegate *del = [[UIApplication sharedApplication]delegate];
        [self dismissModalViewControllerAnimated:YES];
        image = [info objectForKey:UIImagePickerControllerOriginalImage];

        NSLog(@"imagekbgfg=====>%@",image);
        [self.imageView setImage:image];

        imgName = [info objectForKey:UIImagePickerControllerOriginalImage];

        del.mainImgName = imgName;
        del.imageData = UIImageJPEGRepresentation(image, 1.0);
        del.imageApp = image;
    }

    if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera])
    {
       image = [info objectForKey:UIImagePickerControllerOriginalImage];
    }
}

我怎样才能做到这一点？
