Question

ASP.NET中的

异常“不支持给定的文件格式”，in ContentFeed .find({ filter: { where: { "content.value": {regexp: $scope.searchText + '/i'} } } }).$promise，下面是我的代码

QVector<float> values;
int size = lines.size(); 
for(int i=0; i < size; i++)
{
  bool ok=false;
  float value = lines.at(i).toFloat(&ok);
  if(ok)
   values.push_back(value);
}

Answer 1

我认为你还必须插入文件名。

试试这个 -

HttpContext.Current.Response.WriteFile(DocumentPath+ FileName);

<强>更新

试试这行代码

Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("Content-Disposition", "attachment;filename="test.xls");

而不是这个 -

HttpContext.Current.Response.AddHeader("Content-Disposition", "inline; filename=" + FileName);
HttpContext.Current.Response.AddHeader("Content-Type", "application/octet-stream");

更新2

简短的回答是，无法出于安全原因在客户端的计算机上保存文件。所以你能做的只是这一行

Response.AddHeader("Content-Disposition", "attachment;filename="+fileName);

没有DocumentPath。

上次更新

//write file to the server
    string lines = "First line.\r\nSecond line.\r\nThird line.";
            System.IO.StreamWriter file = new System.IO.StreamWriter("test.txt");
          file.WriteLine(lines);

      file.Close();
//read the file from server
      string david = File.ReadAllText("test.txt");

不支持HttpContext.Current.Response.WriteFile路径的格式
