WebClient webClient = new WebClient();
webClient.DownloadFileAsync(new Uri(urlDownload), @"C:\Files\Test\Folder\test.txt");
如果我想将test.txt文件保存到该文件夹,WebClient
仅在我之前创建这些文件夹(Files\Test\Folder)
时保存文件。
但是,例如我没有创建文件夹Test
,Webclient
不会保存任何内容。
如何自动添加文件夹?
答案 0 :(得分:3)
您需要首先检查所需文件夹是否已存在,然后创建它,然后开始下载该文件:
string path = "@C:\Files\Test\Folder";
string filePath = path +"\\test.txt";
if (!Directory.Exists(path))
{
Directory.CreateDirectory(path);
}
WebClient webClient = new WebClient();
webClient.DownloadFileAsync(new Uri(urlDownload),filePath);
更好的是创建一个方法:
private void CreateFolder(string path)
{
if (!Directory.Exists(path))
{
Directory.CreateDirectory(path);
}
}
并称之为:
string path = "@C:\Files\Test\Folder";
string filePath = path +"\\test.txt";
CreateFolder(path);
WebClient webClient = new WebClient();
webClient.DownloadFileAsync(new Uri(urlDownload),filePath);
