无法上传文件丢失System.Web.UI.WebControls.FileUpload

Question

我有一个Web应用程序，我试图给用户上传文件的能力，但是当我测试程序时，这是我得到的错误信息;

Could not find file 'C:\Program Files (x86)\Common Files\Microsoft Shared\DevServer\10.0\System.Web.UI.WebControls.FileUpload'.

我认为这是一些被列入在Visual Studio 2010？

这是一个代码示例;

Dim txtFile As String 

    firstName = FirstNameTextBox.Text 
    lastName = LastNameTextBox.Text 
    empID = EmpIDTextBox.Text 
    newStore = StoreDropDownList.SelectedValue 
    newDate = DateTextBox.Text 
    altDate = Replace(newDate, "/", "_") 
    URL = "https://URL.com/date.pdf" 
    txtFile = PDFFileUpload.ToString 

    Dim userName As String 
    Dim passWord As String 
    Dim tempURL As String 

    userName = "?????" 
    passWord = "?????" 
    tempURL = "https://url.com 

    My.Computer.Network.UploadFile(txtFile, tempURL, userName, passWord, True, 500) 

Answer 1

检查

txtFile = PDFFileUpload.ToString() 

如果你有这个正确的，我相信它可以找到该文件。
