我正在尝试实现一个简单的文件上传,但遇到了一些麻烦。当我对路径进行硬编码时,它可以正常工作。但出于某种原因,当我尝试使用文件上传时,控制器名称将被附加到路径
硬编码路径(我想要得到的):
@"C:\Users\Scott\Documents\The Business\MasterSpinSite\MasterSpin\MasterSpin\LOADME.txt"
路径我收到异常(注意“appz”控制器名称):
C:\Users\Scott\Documents\The Business\MasterSpinSite\MasterSpin\MasterSpin\appz\LOADME.txt'
我的控制器
public ActionResult Load(spinnerValidation theData, HttpPostedFileBase file)
{
if (file.ContentLength > 0)
{
string filePath = Request.MapPath(file.FileName);
string input = System.IO.File.ReadAllText(filePath);
string[] lines = Regex.Split(input, "#!#");
// ...... do stuff
}
我的观点
<form action="" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<input type="submit" value="LOAD ME!">
</form>
可能导致此行为的原因是什么?

您可以节省自己的工作量:
string filename = Request.Files["file"].FileName;
string filePath = Path.Combine(Server.MapPath("~/YourUploadDirectory"), filename);
HttpPostedFileBase postedFile = Request.Files["file"] as HttpPostedFileBase;
postedFile.SaveAs(filePath);
string input = File.ReadAllText(filePath);

试试这个:
public ActionResult Load(spinnerValidation theData, HttpPostedFileBase file)
if (file.ContentLength > 0)
{
var filePath = System.IO.Path.GetFileName(file.FileName);
using (System.IO.StreamReader sr = new System.IO.StreamReader(filePath))
{
var input = sr.ReadToEnd();
var lines = Regex.Split(input, "#!#");
}
}
}
(错误) System.IO.Path.GetFileName(file.FileName)
返回文件名
修改强>
更改System.IO.Path.GetFileName(file.FileName)
Server.MapPath(file.FileName)
public ActionResult Load(spinnerValidation theData, HttpPostedFileBase file)
if (file.ContentLength > 0)
{
var filePath = Server.MapPath(file.FileName);
using (System.IO.StreamReader sr = new System.IO.StreamReader(filePath))
{
var input = sr.ReadToEnd();
var lines = Regex.Split(input, "#!#");
}
}
}
编辑II
或复制到不同的路径:
public ActionResult Load(spinnerValidation theData, HttpPostedFileBase file)
if (file.ContentLength > 0)
{
var fileName = System.IO.Path.GetFileName(file.FileName);
var fileUpload = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName);
file.SaveAs(fileUpload);
if (System.IO.File.Exists(fileUpload))
{
using (System.IO.StreamReader sr = new System.IO.StreamReader(fileUpload))
{
var input = sr.ReadToEnd();
var lines = Regex.Split(input, "#!#");
}
}
}
}
