Question

我在MVC控制器中有以下代码来上传img并将其保存在文件夹中：

library(raster)
library(rasterVis)

## Example data
r <- raster(ncol=4, nrow=2)
r[] <- sample(1:4, size=ncell(r), replace=TRUE)
r <- as.factor(r)

## Add a landcover column to the Raster Attribute Table
rat <- levels(r)[[1]]
rat[["landcover"]] <- c("land","ocean/lake", "rivers","water bodies")
levels(r) <- rat

## Plot
levelplot(r, colorkey=list(height=1), col.regions=rev(terrain.colors(4)), xlab="", ylab="")

这是我在angularjs服务中的代码：

    public ActionResult UploadLogo(HttpPostedFileBase file)
    {


        var path = "";
        if (file != null)
        {

            if (file.ContentLength > 0)
            {
                if (Path.GetExtension(file.FileName).ToLower() == ".jpg" ||
                    Path.GetExtension(file.FileName).ToLower() == ".png" ||
                    Path.GetExtension(file.FileName).ToLower() == ".gif" ||
                    Path.GetExtension(file.FileName).ToLower() == ".jpeg")
                {

                    path = Server.MapPath("~/GroupApp/Content/Images/");

                    if (!Directory.Exists(path))
                    {
                        Directory.CreateDirectory(path);
                    }
                    path = Path.Combine(path, file.FileName);

                    file.SaveAs(path);

                    return new HttpStatusCodeResult(HttpStatusCode.OK);
                }
            }
        }
        return new HttpStatusCodeResult(HttpStatusCode.InternalServerError, ""); // :(
    }

我能说什么，它的效果很好，但为什么在执行这段代码后，整个视图都在刷新？

我的角度控制器中没有任何刷新或视图更改功能。

当我对代码进行调试时，我点击了突破点：＆＃39; file.SaveAs（path）＆＃39;我注意到该页面开始重新加载后。

有人可以向我解释原因吗？那之后如何防止重新加载页面？

Can you remove the timeout function and access the result directly.
Like this

 $http.post(controllerQuery, _file, {
        transformRequest: angular.identity,
        headers: { 'Content-Type': undefined },
        enctype: 'multipart/form-data'

    })
      .then(function (result) {
              deferred.resolve(result);
      },
          function (error) {

              deferred.reject(error);
          });
    return deferred.promise;

};

MVC，Angularjs，HttpPostedFileBase.SaveAs是刷新页面？
