在ASP.NET中创建文件夹并将图像上传到该文件夹​​的最佳方法？

关于如何创建文件夹的任何代码示例在我的根目录中说“pics”，然后将文件上传控件中的图像上传到“pics”文件夹中？ 如果你不想给我所有的代码，我会很高兴有一个很好的链接也告诉我如何在VB.NET中完成（C＃也没关系）。

Answer 1

尝试/抓住你就是:)

public void EnsureDirectoriesExist() { // if the \pix directory doesn't exist - create it. if (!System.IO.Directory.Exists(Server.MapPath(@"~/pix/"))) { System.IO.Directory.CreateDirectory(Server.MapPath(@"~/pix/")); } } protected void Button1_Click(object sender, EventArgs e) { if (FileUpload1.HasFile && Path.GetExtension(FileUpload1.FileName) == ".jpg") { // create posted file // make sure we have a place for the file in the directory structure EnsureDirectoriesExist(); String filePath = Server.MapPath(@"~/pix/" + FileUpload1.FileName); FileUpload1.SaveAs(filePath); } else { lblMessage.Text = "Not a jpg file"; } } 

Answer 2

这是我将如何做到这一点。

  protected void OnUpload_Click(object sender, EventArgs e) { var path = Server.MapPath("~/pics"); var directory = new DirectoryInfo(path); if (directory.Exists == false) { directory.Create(); } var file = Path.Combine(path, upload.FileName); upload.SaveAs(file); }

在文件夹中创建文件夹并上传文件

  DirectoryInfo info = new DirectoryInfo(Server.MapPath(string.Format("~/FolderName/") + txtNewmrNo.Text)); //Creating SubFolder inside the Folder with Name(which is provide by User). string directoryPath = info+"/".ToString(); if (!info.Exists) //Checking If Not Exist. { info.Create(); HttpFileCollection hfc = Request.Files; for (int i = 0; i < hfc.Count; i++) //Checking how many files in File Upload control. { HttpPostedFile hpf = hfc[i]; if (hpf.ContentLength > 0) { hpf.SaveAs(directoryPath + Path.GetFileName(hpf.FileName)); //Uploading Multiple Files into newly created Folder (One by One). } } } else { ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('This Folder already Created.');", true); }
