我正在用Visual Studio Code打开一个文件,例如:
C:/Users/Daniel/Desktop/Code/PTest.py
在我的代码中,我想检查该文件是否打开,就像这样:
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();
}
return false;
}
但是每次我调用此函数时,它都会返回false
,因此它从未使用过。
我在做什么错了?
