推荐答案

您可以尝试以下文件属性:

You could try the following for the file attribute:

FileInfo fileInfo = new FileInfo(@"path\to\file"); 
if (fileInfo.IsReadOnly) 
{ 
    // do something 
} 

或是否要检查文件是否正在使用中:

or if you want to check if the file is in use:

protected virtual bool IsFileLocked(FileInfo file) 
{ 
    FileStream stream = null; 
 
    try 
    { 
        stream = file.Open(FileMode.Open, FileAccess.ReadWrite, FileShare.None); 
    } 
    catch (IOException) 
    { 
        //the file is unavailable because it is: 
        //still being written to 
        //or being processed by another thread 
        //or does not exist (has already been processed) 
        return true; 
    } 
    finally 
    { 
        if (stream != null) 
            stream.Close(); 
    } 
 
    //file is not locked 
    return false; 
}
