System.Net.WebException：远程服务器返回错误：（500）内部服务器错误。

Question

System.Net.WebException：远程服务器返回错误：（500）内部服务器错误。在System.Net.HttpWebRequest.GetResponse（）在SMS.Testpage.btnsubmit_Click（对象发件人，EventArgs e）

这是我得到当我上传我的文件到远程服务器的错误。在本地主机的情况下，它工作正常，并返回我期待的相同的扫描笏，但我不明白为什么它的行为是这样的，如果有人对我的错误有想法，请让我摆脱这个大问题。自3周以来，我一直在努力解决这个问题。

这里是我的web配置的代码---当它在服务器运行

Answer 1

您的代码崩溃。你需要获得更多关于它为什么会崩溃的细节，以便解决它。首先要做的是更新Web配置，以便它可以提供有关错误的更多详细信息。设置的customErrors元素的模式属性值设置为“关”

<system.web> 
    <customErrors mode="Off" /> 
    //Other items goes here 
</system.web> 

我能想到的，可能的原因是

1. 你有一个不正确的连接字符串。有些代码不是 能够访问您的数据库服务器。仔细检查数据库服务器的名称是否为 正确。

2. 该代码没有写入某个目录的权限（当您执行文件上载时，需要确保目录权限已更新，以便ASP.NET可以写入该文件夹）。
