检索"我的电脑"中存在的所有pdf文件

Question

我有以下代码从MyComputer检索所有pdf文件.但我得到的错误如下.是否可以使用C#代码从一台计算机中检索所有pdf文件.

string path = Environment.GetFolderPath(Environment.SpecialFolder.MyComputer);            
System.IO.DirectoryInfo dir = new System.IO.DirectoryInfo(path); // Error : The path is not of a legal form.
IEnumerable<System.IO.FileInfo> fileList = dir.GetFiles("*.pdf", System.IO.SearchOption.AllDirectories);

Answer 1

您可以获取所有驱动器,然后获取所有文件.

编辑:你也可以使用Directory.EnumerateFiles方法,让你获得文件路径,你可以在列表中添加.这将为您List<string>提供所有文件路径.喜欢:

List<string> filePathList = new List<string>();
foreach (DriveInfo drive in DriveInfo.GetDrives())
{
    try
    {
        var filenames = Directory.EnumerateFiles(drive.Name, "*.pdf", SearchOption.AllDirectories);
        foreach (string fileName in filenames)
        {
            filePathList.Add(fileName);
        }
    }
    catch (FieldAccessException ex)
    {

        //Log, handle Exception
    }
    catch (UnauthorizedAccessException ex)
    {
        //Log, handle Exception
    }
    catch (Exception ex)
    {
        //log , handle all other exceptions
    }
}

老答案.

List<FileInfo> fileList = new List<FileInfo>();
foreach (var drive in System.IO.DriveInfo.GetDrives())
{
    try
    {
        DirectoryInfo dirInfo = new DirectoryInfo(drive.Name);
        foreach (var file in dirInfo.GetFiles("*.pdf", SearchOption.AllDirectories))
            fileList.Add(file);

    }
    catch (FieldAccessException ex)
    {

        //Log, handle Exception
    }
    catch (UnauthorizedAccessException ex)
    {
        //Log, handle Exception
    }
    catch (Exception ex)
    {
        //log , handle all other exceptions
    }
}
