C# 依次读取某目录下文件文件名

能，最简单物余的方法使用DirectoryInfo

DirectoryInfo source = new DirectoryInfo(@"c:\MyDir")

foreach (DirectoryInfo diSourceSubDir in source.GetDirectories()) {

//罩蠢滚这里判断diSourceSubDir根据diSourceSubDir.Name来决定放在哪个集合档银中。

}

#include <stdio.h>

#include <memory.h>

#include <string>

int main()

{

char filename[32]

char outfile[32]

scanf("%s", filename)

FILE *fp=fopen(filename, "r"型和卜), *ofp=fopen(outfile, "w"卜穗)

return 0

}

一个简单的读取文棚虚件，你可以仿照这个来读你的文件

给出 临时工作文件名和路径，要查的文件夹路径和文件夹名。

用 DOS 命令获文件名

#include <stdio.h>

#include <stdlib.h>

#define Buff_size 4096

FILE *fin

void main (int argc, char *argv[])

{

char current_dir[72], namelist[72],current_file_name[72]

char command[200]

int i,j,n=0

char *buff

buff = (char *) malloc( Buff_size * sizeof (char))

if (!buff) {

printf("\007No enough memory -- Can not alloc the Buff\n")

exit(2)

}

strcpy(namelist,"C:\\temp\\abc.lis") // 临时工作文件名槐键和路径

strcpy(current_dir, "运明厅D:\\zzz") //要查的文件夹路径和文件夹名

sprintf(command,"DIR/B/A-D %s >%s", current_dir, namelist)

system(command)

if ( (fin = fopen(namelist,"r") ) == NULL ) {

printf("\007Cann'旁隐t open work file: %s ", namelist)exit(1)

}

while ( fgets( current_file_name, 72, fin) !=NULL ) n=n+1

rewind(fin)

printf("\007total %d files\n",n)

for (i=0i<ni++){

if ( fgets( current_file_name, 72, fin) ==NULL) exit(0)

printf("%s",current_file_name)

}

exit(0)

}
