这个vb.net代码(几行用来递归搜索文件的代码)翻译成c#报错,要怎么改呢?

[wnujy611861]

菜鸟,求帮忙.几行用来递归搜索文件的代码. 多谢!!
机器自动翻译后的c#(报错的地方见注释部分):

	
private static string[] FoundFile;
private static long Ntx;
public static string[] SearchFileInPath(string thePath, string theFileName, bool mStop = false)//--------------这里 mStop As Boolean = False 报错
	{
		if (Strings.Right(thePath, 1) != "\\")
			thePath = thePath + "\\";
		GetFileLoop(thePath, theFileName, mStop);
		return FoundFile;
	}

	private static string GetFileLoop(string CurrentPath, string SearFile, bool mStop = false)//-------这里 mStop As Boolean = False 也报错
	{
		string functionReturnValue = null;
		int nI = 0;
		int nDirectory = 0;
		long i = 0;
		string sFileName = null;
		string[] sDirectoryList = null;
		sDirectoryList = new string[-1 + 1];
		
		 // ERROR: Not supported in C#: OnErrorStatement

		sFileName = FileSystem.Dir(CurrentPath, Constants.vbHidden | Constants.vbDirectory | Constants.vbReadOnly | Constants.vbSystem);//--------------FileSystem.Dir在c#中是什么函数呢?Constants.也报错
		while (!string.IsNullOrEmpty(sFileName)) {
			if (Strings.UCase(sFileName) // ERROR: Unknown binary operator Like//------------这里问题大了,要怎么改呢
) {
				i = FileSystem.GetAttr(CurrentPath + sFileName);
				if ((i & Constants.vbDirectory) == 0) {
					if (mStop == false) {
						Array.Resize(ref FoundFile, Ntx + 1);
						FoundFile[Ntx] = CurrentPath + sFileName;
						Ntx = Ntx + 1;
					//Application.DoEvents()
					//Sleep(5)
					} else {
						functionReturnValue = CurrentPath + sFileName;
						return functionReturnValue;
					}
				}
			}
			if (sFileName != "." & sFileName != "..") {

				if (FileSystem.GetAttr(CurrentPath + sFileName) & Constants.vbDirectory) {
					nDirectory = nDirectory + 1;
					Array.Resize(ref sDirectoryList, nDirectory + 1);//--------错误	283	与“System.Array.Resize<string>(ref string[], int)”最匹配的重载方法具有一些无效参数,要怎么改呢?
					sDirectoryList[nDirectory] = CurrentPath + sFileName;
				}
			}
			sFileName = FileSystem.Dir();
		}
		for (nI = 1; nI <= nDirectory; nI++) {
			functionReturnValue = GetFileLoop(sDirectoryList[nI] + "\\", SearFile);
			if (!string.IsNullOrEmpty(functionReturnValue) & mStop == true)
				break; // TODO: might not be correct. Was : Exit For//这里应该是exit for吧?
		}
		return functionReturnValue;
	}

不需要这么麻烦，
System.IO.Directory.GetFiles(
string path,
string searchPattern,
SearchOption searchOption /* AllDirectories 为递归子文件夹 */
);

[/Quote]谢谢!它这个有没有权限限制什么的?就是如果文件权限限制了会不会不返回任何结果什么的?
