}|code-block|syntax|javascript|2590629|它看起来没有你的代码那么复杂。通过查看文件夹中每个条目的dirent结构，应该很容易找出它是否是一个目录，如果是，则中止。然后将printf更改为文件的某种delete语句。|2590630|您可能需要调用stat来告知文件或目录。|2590631|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

Here is a simple program to list all files and directories in a folder: 

<pre><code>#include &lt;stdio.h&gt;
#include &lt;dirent.h&gt;

int main(void)
{
 struct dirent *de; // Pointer for directory entry

 // opendir() returns a pointer of DIR type. 
 DIR *dr = opendir(".");

 if (dr == NULL) // opendir returns NULL if couldn't open directory
 {
 printf("Could not open current directory" );
 return 0;
 }

 while ((de = readdir(dr)) != NULL)
 printf("%s\n", de-&gt;d_name);

 closedir(dr); 
 return 0;
}
</code></pre>

It seems less complicated than your code.
It should be easy to find out by looking at the dirent structure for each entry in the folder whether or not it is a directory and if so abort. Then change the printf to some kind of delete statement for the files. 

You may need to call stat to tell file or directory.

As the solution says, please be careful when using this function and make sure that you double null terminate <code>pFrom</code>.

<pre><code>dir_name[STR_SIZE];
int dir_exists = 0;
snprintf(dir_name, STR_SIZE, "folder/dir_to_be_deleted");

// Check if directory exists
DWORD dwAttrib = GetFileAttributes(dir_name);
if (dwAttrib != INVALID_FILE_ATTRIBUTES &amp;&amp; (dwAttrib &amp; FILE_ATTRIBUTE_DIRECTORY)) {
 dir_exists = 1;
}

if (dir_exists == 1) {

 // Remove contents of directory 
 snprintf(dir_name, STR_SIZE, "%s/%s", LOCAL_DIR, tokens[1]);
 TCHAR szDir[MAX_PATH];
 StringCchCopy(szDir, MAX_PATH, dir_name);
 StringCchCat(szDir, MAX_PATH, TEXT("\\*"));

 int len = _tcslen(szDir);
 TCHAR* pszFrom = malloc((len + 4) * sizeof(TCHAR)); //4 to handle wide char
 StringCchCopyN(pszFrom, len + 2, szDir, len + 2);
 pszFrom[len] = 0;
 pszFrom[len + 1] = 0;

 SHFILEOPSTRUCT fileop;
 fileop.hwnd = NULL; // no status display
 fileop.wFunc = FO_DELETE; // delete operation
 fileop.pFrom = pszFrom; // source file name as double null terminated string
 fileop.pTo = NULL; // no destination needed
 fileop.fFlags = FOF_NOCONFIRMATION | FOF_SILENT; // do not prompt the user
 fileop.fAnyOperationsAborted = FALSE;
 fileop.lpszProgressTitle = NULL;
 fileop.hNameMappings = NULL;

 if (SHFileOperation(&amp;fileop) != 0) {
 printf("Error SHFileOperation\n");
 return 0;
 }
 free(pszFrom);

 // Remove directory
 if ((RemoveDirectory(dir_name)) == 0) {
 printf("Error removing dictionary\n");
 return 0;
 }
}

Here is a simple windows batch file that will do the job. 

<pre><code>@echo off
echo (batch file to remove a directory on windows)
cd /d %tmp%
for /d %%i in (*) do (echo this directory contains a folder "%%i") &amp; (echo so it cannot be deleted) &amp; (goto :END)
for /r %%i in (*) do (echo del %%i)
:END 
</code></pre>

Change the 3rd line to use your directory. Remove 'echo' on line 5.
If you are locked into using 'c' you can use 'system()' to run it.

I am wanting to delete a directory in C, Windows. I understand that I must first delete all files within the directory, which is the part that I am confused about. I have found <code>SHFileOperation</code> and <code>IFileOperation</code> although I don't understand how they are implemented from the documentation.

My current implementation:

<pre><code>int dir_exists = 0;
snprintf(dir_name, STR_SIZE, "%s\\%s", LOCAL_DIR, tokens[1]);

// Check if directory exists
DWORD dwAttrib = GetFileAttributes(dir_name);
if (dwAttrib != INVALID_FILE_ATTRIBUTES &amp;&amp; (dwAttrib &amp; FILE_ATTRIBUTE_DIRECTORY)) {
 dir_exists = 1;
}

if (dir_exists == 1) {

 // Remove contents of directory (CURRENTLY UNIX)
 DIR *dir;
 struct dirent *d;
 char filepath[FNAME_SIZE];
 dir = opendir(dir_name);
 while (d = readdir(dir)) {
 sprintf(filepath, "%s/%s", dir_name, d-&gt;d_name);
 remove(filepath);
 }

 // Remove directory
 if ((RemoveDirectory(dir_name)) == 0) {
 printf("Error removing dictionary\n");
 return 0;
 }
}
</code></pre>

I am wanting a Windows replacement to the section commented WITHOUT use of <code>#include &lt;dirent.h&gt;</code> as my VS does not have this header file:

<pre><code>// Remove contents of directory (CURRENTLY UNIX)
</code></pre>

Delete directory in C

Windows

我想在C，Windows中删除一个目录。我知道我必须首先删除目录中的所有文件，这是我感到困惑的部分。我找到了SHFileOperation和IFileOperation，尽管我不明白它们是如何从文档中实现的。我目前的实现：int dir_exists = 0;snprintf(dir_name, STR_SIZE, "...
