处理上传的文件而不保存它？
我正在使用以下代码上传文件，
[HttpPost]
public ActionResult ImportDeleteCourse(ImportFromExcel model)
{
var excelFile = model.ExcelFile;
if (ModelState.IsValid)
{
OrganisationServices services = new OrganisationServices();
string filePath = Path.Combine(HttpContext.Server.MapPath("../Uploads"),
Path.GetFileName(excelFile.FileName));
excelFile.SaveAs(filePath);
// ... snipped //
}
}
我实际上不需要存储上传的 Excel 文件。无论如何我可以在不保存的情况下处理它吗？
注意：ImportFromExcel 类只不过是一个模型，基本上是：
public class ImportFromExcel
{
[Required(ErrorMessage = "Please select an Excel file to upload.")]
[DisplayName("Excel File")]
public HttpPostedFileWrapper ExcelFile { get; set; }
}
最有趣的部分是它包装了 HttpPostedFileWrapper。
I am uploading a file using the following code
[HttpPost]
public ActionResult ImportDeleteCourse(ImportFromExcel model)
{
var excelFile = model.ExcelFile;
if (ModelState.IsValid)
{
OrganisationServices services = new OrganisationServices();
string filePath = Path.Combine(HttpContext.Server.MapPath("../Uploads"),
Path.GetFileName(excelFile.FileName));
excelFile.SaveAs(filePath);
// ... snipped //
}
}
I do not really need to do store the uploaded excel file. Is there anyway I can process it without saving?
Note: The ImportFromExcel class is nothing but a model, which is basically:
public class ImportFromExcel
{
[Required(ErrorMessage = "Please select an Excel file to upload.")]
[DisplayName("Excel File")]
public HttpPostedFileWrapper ExcelFile { get; set; }
}
The most interesting part is that it wraps a HttpPostedFileWrapper.

当然可以。正如 Patko 所建议的，InputStream 属性可用于另一个流。例如，我对上传的 xml 文档执行了此操作，以便与 LINQ to XML 一起使用：

Sure you can. As Patko suggested, the InputStream property can be used for another stream. For example I did this for an uploaded xml document to use with LINQ to XML:

HttpPostedFileBase.InputStream 属性看起来很有前途。您应该能够使用它并将数据保存到您需要的任何其他流。
The HttpPostedFileBase.InputStream property looks promising. You should be able to use that and save the data to whichever other stream you need to.
