foreach (string fileName in System.IO.Directory.GetFiles(path))
{
System.IO.FileInfo fileInfo = new System.IO.FileInfo(fileName);
fileInfo.Attributes |= System.IO.FileAttributes.ReadOnly;
// or
fileInfo.IsReadOnly = true;
}

Use File.SetAttributesin a loop iterating over Directory.GetFiles
在遍历Directory.GetFiles的循环中使用File.SetAttributes

You can try this : iterate on each file and subdirectory :
你可以试试这个：迭代每个文件和子目录：
public void Recurse(DirectoryInfo directory)
{
foreach (FileInfo fi in directory.GetFiles())
{
fi.IsReadOnly = false; // or true
}
foreach (DirectoryInfo subdir in directory.GetDirectories())
{
Recurse(subdir);
}
}

If you wanted to remove the readonly attributes using pattern matching (e.g. all files in the folder with a .txt extension) you could try something like this:
如果您想使用模式匹配删除只读属性（例如文件夹中带有 .txt 扩展名的所有文件），您可以尝试以下操作：
Directory.EnumerateFiles(path, "*.txt").ToList().ForEach(file => new FileInfo(file).Attributes = FileAttributes.Normal);
