代码:

        {
            string sourceDir = @"c:'source";//folder directory path//
            try
            {
                var txtFiles = Directory.EnumerateFiles(sourceDir, "*.*", SearchOption.AllDirectories).Where(s => s.EndsWith(".jpg") || s.EndsWith(".bmp") || s.EndsWith(".png") || s.EndsWith(".gif") || s.EndsWith("jpeg"));//identify extension name//
                foreach (string currentFile in txtFiles)
                {
                    string fileName = currentFile.Substring(sourceDir.Length + 1);
                    Directory.GetFiles(currentFile, Path.GetExtension(fileName));
                    Directory.GetFiles(currentFile, Path.GetFileName(fileName));
                    Directory.GetFiles(currentFile,  Path.GetFileNameWithoutExtension(fileName));
                }  
            }
        }
    }
}//get files//

这里是我的代码if,用于导航文件和复制文件(如果存在)

您在try-catch中丢失了catch{}块。

您需要在Try块的末尾添加catch块

 try
    {
        var txtFiles = Directory.EnumerateFiles(sourceDir, "*.*", SearchOption.AllDirectories).Where(s => s.EndsWith(".jpg") || s.EndsWith(".bmp") || s.EndsWith(".png") || s.EndsWith(".gif") || s.EndsWith("jpeg"));//identify extension name//

        foreach (string currentFile in txtFiles)
        {
            string fileName = currentFile.Substring(sourceDir.Length + 1);
            Directory.GetFiles(currentFile, Path.GetExtension(fileName));
            Directory.GetFiles(currentFile, Path.GetFileName(fileName));
            Directory.GetFiles(currentFile,  Path.GetFileNameWithoutExtension(fileName));
        }  
    }catch (IOException e)
    {
        //TODO Something
    }

添加捕获块

class Program
{
static void Main()
{
    string sourceDir = @"c:'source";//folder directory path//

    try
    {
        var txtFiles = Directory.EnumerateFiles(sourceDir, "*.*", SearchOption.AllDirectories).Where(s => s.EndsWith(".jpg") || s.EndsWith(".bmp") || s.EndsWith(".png") || s.EndsWith(".gif") || s.EndsWith("jpeg"));//identify extension name//

        foreach (string currentFile in txtFiles)
        {
            string fileName = currentFile.Substring(sourceDir.Length + 1);
            Directory.GetFiles(currentFile, Path.GetExtension(fileName));
            Directory.GetFiles(currentFile, Path.GetFileName(fileName));
            Directory.GetFiles(currentFile,  Path.GetFileNameWithoutExtension(fileName));
        }  
    }
    catch(Exception ex) // Added
    {
    }
}

}

您缺少catch

static void Main()
 {
        string sourceDir = @"c:'source";//folder directory path//
    try
    {
        //code here
    }
    catch (Exception ex)
    {
        //if an error occurs with in the try block, it will handled here.
    }
