解决方法
我不记得我在哪里找到了这个代码,但它是使用pInvoke的替代方案,我觉得这个任务有点过分.使用FileSystemWatcher查看文件夹,当事件触发时,您可以使用以下代码确定哪个用户更改了文件：
private string GetSpecificFileProperties(string file,params int[] indexes)
{
string fileName = Path.GetFileName(file);
string folderName = Path.GetDirectoryName(file);
Shell32.Shell shell = new Shell32.Shell();
Shell32.Folder objFolder;
objFolder = shell.NameSpace(folderName);
StringBuilder sb = new StringBuilder();
foreach (Shell32.FolderItem2 item in objFolder.Items())
{
if (fileName == item.Name)
{
for (int i = 0; i < indexes.Length; i++)
{
sb.Append(objFolder.GetDetailsOf(item,indexes[i]) + ",");
}
break;
}
}
string result = sb.ToString().Trim();
//Protection for no results causing an exception on the `SubString` method
if (result.Length == 0)
{
return string.Empty;
}
return result.Substring(0,result.Length - 1);
}
Shell32是对DLL的引用：Microsoft Shell控件和自动化 – 它是一个COM引用
string Type = GetSpecificFileProperties(filePath,2); string ObjectKind = GetSpecificFileProperties(filePath,11); DateTime CreatedDate = Convert.ToDateTime(GetSpecificFileProperties(filePath,4)); DateTime LastModifiedDate = Convert.ToDateTime(GetSpecificFileProperties(filePath,3)); DateTime LastAccessDate = Convert.ToDateTime(GetSpecificFileProperties(filePath,5)); string LastUser = GetSpecificFileProperties(filePath,10); string ComputerName = GetSpecificFileProperties(filePath,53); string FileSize = GetSpecificFileProperties(filePath,1);
