C#中FolderBrowserDialog fbd = new FolderBrowserDialog();下如何解决新建文件夹重命名并保存文件的问题！急！

private BlockLength _BlockLength;
private Byte _BlockCount;
private Boolean _AutoRun;
private Thread _thread;
private String _FilePath;

private void btn_ReadAndSave_Click(object sender, EventArgs e)
{
if (btn_ReadAndSave.Text.Equals("Inventory Read And Save"))
{
if (cmd_Length_6.SelectedIndex < 0)
{
AddList("错误：请选择正确的数据块长度！");
cmd_Length_6.Focus();
return;
}
else
{
_BlockLength = (BlockLength)Byte.Parse(cmd_Length_6.Text.Trim());
}
try

Thread.Sleep(500);
_thread.Abort();

}
}
///以上是淡季按钮后显示系统文件菜单浏览，能选择文件夹并保存
private void InventoryReadSave()
{
Int32 TagCount = 0;
String[] TagNumber = new String[0];
Byte value;
String RvsTag;
while (_AutoRun)
{

if (value != 0x00)
{
continue;
}
AddList(String.Format("Inventory执行成功，找到了{0}个卡片：", TagCount));
foreach (String Tag in TagNumber)
{
RvsTag = "";//文件名
for (int i = 0; i < 8; i++)
{ RvsTag += Tag.Substring((7 - i) * 2, 2); }
String FileName = _FilePath +"\\"+ RvsTag + ".txt";
using (FileStream fs = new FileStream(FileName, FileMode.OpenOrCreate, FileAccess.Write))
{
using (StreamWriter sw = new StreamWriter(fs, Encoding.Default))
{
//Byte BlockAddress = 0;
Byte[] BlockData = new Byte[1];
AddList(String.Format("开始读取标签:{0}", RvsTag));
sw.WriteLine(String.Format("*{0}*", RvsTag));

for (Byte i = 0; i < _BlockCount; i++)
{
value = reader.ReadSingleBlock(Tag, _BlockLength, i, ref BlockData);
if (value == 0x00)
{
String data = "";
for (Int32 ii = 0; ii < BlockData.Length; ii++)
{
data += BlockData[ii].ToString("X2");
}

AddList(String.Format("第{0}块数据读取成功:{1}", i, data));

sw.WriteLine(data);
}
else
{
AddList(String.Format("ReadSingleBlock命令执行失败！错误代码：0x{0:X2}", value));
}
}

}
}

}
AddList("标签读取完毕，请移除所有标签，然后放入新的标签。\r\n1秒钟后将开始新的读取。");
Thread.Sleep(1000);
}
--------------------------------------上面是文件保存并写入，但时出现了问题文件写入成功，但是却存不到前面新建的文件夹里而是和文件夹在同一级目录并存，二新建文件夹里没文件。

找不到回复的骂我后来找到原因，在 FolderBrowserDialog fbd = new FolderBrowserDialog(); if (fbd.ShowDialog() == DialogResult.OK) { _FilePath = fbd.SelectedPath+"//"; //加一个“//” } 但是跳到 private void InventoryReadSave() { Int32 TagCount = 0; String[] TagNumber = new String[0]; Byte value; String RvsTag; while (_AutoRun) { value = reader.Inventory(ModulateMethod.ASK, InventoryModel.Multiple, ref TagCount, ref TagNumber); if (value != 0x00) { //AddList(String.Format("错误：Inventory命令执行失败，错误代码：0x{0:X2}！", value)); Thread.Sleep(500); ///到这就不往下走了，又跳到上一级，郁闷 continue; 死活走不到下面这块 AddList(String.Format("Inventory执行成功，找到了{0}个卡片：", TagCount)); foreach (String Tag in TagNumber) { RvsTag = ""; for (int i = 0; i < 8; i++) { RvsTag += Tag.Substring((7 - i) * 2, 2); } String FileName = String.Format("{0}{1}.txt", _FilePath + "\\", RvsTag); using (FileStream fs = new FileStream(FileName, FileMode.OpenOrCreate, FileAccess.Write)) { using (StreamWriter sw = new StreamWriter(fs, Encoding.Default))

你这有个continue; 当然不往下走了，又跳到上一级
