C++使用通配符查找文件(FindFirstFile)

Posted 2021-12-01 chay

调用 FindFirstFile 和 FindNextFile 可搜索某个目录下的相应文件。

BOOL SearchFilesByWildcard(WCHAR *wildcardPath)
{
    HANDLE hFile = INVALID_HANDLE_VALUE; 
    WIN32_FIND_DATA pNextInfo;  
 
    hFile = FindFirstFile(wildcardPath,&pNextInfo); 
    if(INVALID_HANDLE_VALUE == hFile)  
    {  
        return FALSE;  
    }  
 
    WCHAR infPath[MAX_PATH] = {0};
    if(pNextInfo.cFileName[0] != '.')
    {
        printf("Find result = %ws\r\n",pNextInfo.cFileName);
    }
 
    while(FindNextFile(hFile,&pNextInfo))  
    {  
        if(pNextInfo.cFileName[0] == '.')
        {
            continue;  
        }
 
        printf("Find result = %ws\r\n",pNextInfo.cFileName);
    }
 
    return FALSE;
}

int main(int argc,char* argv[])
{
    setlocale(LC_ALL,"chs");
 
    //查找 abc开头的txt文件
    printf("Search 1:\r\n");
    SearchFilesByWildcard(L"E:\\Test\\abc*.txt");
    printf("\r\n");
 
    //查找 abc开头的文件
    printf("Search 2:\r\n");
    SearchFilesByWildcard(L"E:\\Test\\abc*");
    printf("\r\n");
 
    //查找jnt文件
    printf("Search 3:\r\n");
    SearchFilesByWildcard(L"E:\\Test\\*.jnt");
    printf("\r\n");
 
    //查找文件名为4个字符的txt文件
    printf("Search 4:\r\n");
    SearchFilesByWildcard(L"E:\\Test\\????.txt");
    printf("\r\n");
 
    //查找包含"档案"的文件
    printf("Search 5:\r\n");
    SearchFilesByWildcard(L"E:\\Test\\*档案*");
    printf("\r\n");
 
    getchar();
    return 0;
}
