如何防止母版页标题被缓存？ [英] How to prevent master page header getting cached?

问题描述

我的要求是从我的项目文件夹下载文件..我写了以下代码：







<前lang =c＃> 受保护 void btnOpenSampleExcel_Click（ object sender，EventArgs e）
{
尝试
{
string fileName = SampleRetsServerCredentials.csv;
string filePath = Server.MapPath（ /SampleRetsCredential\\SampleRetsServerCredentials.csv）;
Response.AppendHeader（ content-disposition， filename = + fileName）;
Response.ContentType = application / octet-stream;
Response.WriteFile（filePath， false ）;
}

catch （例外情况）
{
_alertMessage = 抱歉，现在无法显示示例文件！请稍后再试。;
radManager.RadAlert（ message， 400 ， null ， title， null ）;
}
}

下载工作正常，但主页面标题部分也在下载后显示在csv中。我怎样才能防止这种行为。



谢谢，

解决方案

在写入文件流之前，请先清除您的回复。



例如

   Response.Clear（）;   
 Response.AppendHeader（  content-disposition，  filename = + fileName ）; 
 Response.ContentType =   application / octet-stream; 
 Response.WriteFile（filePath， false ）; 

Hi,

My requirement was to download a file from my project folder.. i wrote the following code:

protected void btnOpenSampleExcel_Click(object sender, EventArgs e)
{
    try
    {
        string fileName = "SampleRetsServerCredentials.csv";
        string filePath = Server.MapPath("/SampleRetsCredential\\SampleRetsServerCredentials.csv");
        Response.AppendHeader("content-disposition", "filename=" + fileName);
        Response.ContentType = "application/octet-stream";
        Response.WriteFile(filePath, false);
    }

    catch (Exception ex)
    {
        _alertMessage = "Sorry, cant show the sample file now! Please try after some time.";
        radManager.RadAlert("message", 400, null, "title", null);
    }
}

Download is working correctly, but the Master page header portion is also shown in the csv after downloading.. How can i prevent such a behaviour.

Thanks,
Amrutha.

解决方案

Hi,

Just clear your response before write the file stream.

e.g.

Response.Clear();
Response.AppendHeader("content-disposition", "filename=" + fileName);
Response.ContentType = "application/octet-stream";
Response.WriteFile(filePath, false);
