如何在C＃中创建目录 [英] How to Create Directory in C#

问题描述

如何从inpur路径自动创建目录以获取文件？

解决方案

  if （！Directory.Exists（directory））
 {
 Directory.CreateDirectory（directory）; 
} 

谢谢

 DirectoryInfo src =  new  DirectoryInfo（ @  E：\ Test \\ \\Dir1\" ）; 
 DirectoryInfo dest =  new  DirectoryInfo（ @  C：\Dir2\" ）; 
 CopyDirectory（src，dest）; 
 
 
 静态  void  CopyDirectory（DirectoryInfo源，DirectoryInfo目标） 
 {
  if （！destination.Exists）
 {
 destination.Create（）; 
} 
 
  //  复制所有文件。  
 FileInfo [] files = source.GetFiles（）; 
  foreach （FileInfo文件 in  files）
 {
 file。 CopyTo（Path.Combine（destination.FullName，
 file.Name））; 
} 
 
  //  处理子目录。  
 DirectoryInfo [] dirs = source.GetDirectories（）; 
  foreach （DirectoryInfo dir  in  dirs）
 {
  //  获取目标目录。  
  string  destinationDir = Path.Combine（destination.FullName，dir.Name）; 
 
  //  递归调用CopyDirectory（）。  
 CopyDirectory（dir， new  DirectoryInfo（destinationDir））; 
} 
} 

public void Getpr（）

{

DateTime dt = DateTime.Now;



string [] files = Directory.GetFiles（file Name，*。*，SearchOption.AllDirectories）;

int checkCount = files.Length;

foreach（文件中的字符串文件）

{

//等待免费限制......

而（workingCounter> = workingLimit）

{

Thread.Sleep（100）;

}

workingCounter + = 1;

ParameterizedThreadStart pts = new ParameterizedThreadStart（ProcessFile）;

线程th =新线程（pts）;

th.Start（file）;

}

//等待所有线程完成...

while（processedCounter< checkCount）

{

Thread.Sleep（100）;

}



DateTime dt1 = DateTime.Now;

TimeSpan t = dt1 - dt;

MessageBox.Show（工作完成！+ t.TotalMinutes.ToString（）+ ）;

}



public void ProcessFile（目标文件）

{

try

{

string strpath = Path.GetRandomFileName（）;

if（！Directory.Exists（Directory name+ strpath） ））

{

Directory.CreateDirectory（目录名称+ strpath）;

}



//为演示做一些睡眠......

Thread.Sleep（1000）;

}

catch（例外情况除外）

{

//处理你的异常...

string exMsg = ex.Message;

}

终于

{

Interlocked.Decrement（ref workingCounter）;

Interlocked.Increment（ref processedCounter）;

}

}

how to Automatically create directories from inpur path to get files?

解决方案

if (!Directory.Exists(directory))
            {
                Directory.CreateDirectory(directory);
            }

Thanks

DirectoryInfo src = new DirectoryInfo(@"E:\Test\Dir1"); 
DirectoryInfo dest = new DirectoryInfo(@"C:\Dir2"); 
CopyDirectory(src, dest); 
 
 
static void CopyDirectory(DirectoryInfo source, DirectoryInfo destination) 
        { 
            if (!destination.Exists) 
            { 
                destination.Create(); 
            } 
 
            // Copy all files. 
            FileInfo[] files = source.GetFiles(); 
            foreach (FileInfo file in files) 
            { 
                file.CopyTo(Path.Combine(destination.FullName, 
                    file.Name)); 
            } 
 
            // Process subdirectories. 
            DirectoryInfo[] dirs = source.GetDirectories(); 
            foreach (DirectoryInfo dir in dirs) 
            { 
                // Get destination directory. 
                string destinationDir = Path.Combine(destination.FullName, dir.Name); 
 
                // Call CopyDirectory() recursively. 
                CopyDirectory(dir, new DirectoryInfo(destinationDir)); 
            } 
        }

public void Getpr()
{
DateTime dt = DateTime.Now;

string[] files = Directory.GetFiles("file Name", "*.*", SearchOption.AllDirectories);
int checkCount = files.Length;
foreach (string file in files)
{
//wait for free limit...
while (workingCounter >= workingLimit)
{
Thread.Sleep(100);
}
workingCounter += 1;
ParameterizedThreadStart pts = new ParameterizedThreadStart(ProcessFile);
Thread th = new Thread(pts);
th.Start(file);
}
//wait for all threads to complete...
while (processedCounter < checkCount)
{
Thread.Sleep(100);
}

DateTime dt1 = DateTime.Now;
TimeSpan t = dt1 - dt;
MessageBox.Show("Work completed!" + t.TotalMinutes.ToString() + " ");
}

public void ProcessFile(object file)
{
try
{
string strpath = Path.GetRandomFileName();
if (!Directory.Exists("Directory name" + strpath))
{
Directory.CreateDirectory("Directory name" + strpath);
}

//make some sleep for demo...
Thread.Sleep(1000);
}
catch (Exception ex)
{
//handle your exception...
string exMsg = ex.Message;
}
finally
{
Interlocked.Decrement(ref workingCounter);
Interlocked.Increment(ref processedCounter);
}
}
