我已经为所工作的公司制作了Windows Forms应用程序。 在我自己的笔记本电脑和PC上，该程序可以正常运行，但是当我尝试在公司的计算机上安装该程序时，出现了很大的错误。
我使用.NET Framework 4.6.1创建了程序，而我工作的公司PC上的当前Framework是4.0版。由于版本的差异，我遇到了一些错误。我已经解决了所有错误，除了一个...
我想从Web服务器（000webhost服务器）上的本地存储数据进行备份。同样，所有这些在我自己的笔记本电脑上都可以正常工作，即使我在公司的WIFI上连接，在我自己的计算机上也可以正常工作。但是在公司的PC上，一切都变了。.当尝试进行备份时，我总是遇到异常。
我已经在Google上搜索了任何解决方案，但不幸的是没有运气。只有一个结果告诉我有关此异常的任何信息，该家伙写道HttpClient对象应该是静态的，我不应该使用using（）子句。
我当前的代码：
private static HttpClient client;
public Parser(Form1 form)
{
client = new HttpClient();
}
private async Task<int> backup()
{
try
{
var data = new FormUrlEncodedContent(new[]
{
new KeyValuePair<string, string>("license", license),
new KeyValuePair<string, string>("json", text),
new KeyValuePair<string, string>("date", DateTime.Today.ToString("dd/MM/yyyy"))
});
var response = await client.PostAsync(URL + "makebackup.php", data);
string content = await response.Content.ReadAsStringAsync();
Response result = JsonConvert.DeserializeObject<Response>(content);
return result.result;
}
catch (HttpRequestException)
{
form.showMessageBox("Kon geen backup maken door het ontbreken van een internet verbinding");
}
return -1;
}
public async Task<CheckVersionResult> checkVersion()
{
try
{
var data = new FormUrlEncodedContent(new[]
{
new KeyValuePair<string, string>("version", form.mrtVersion)
});
var response = await client.PostAsync(URL + "checkversion.php", data);
string content = await response.Content.ReadAsStringAsync();
CheckVersionResult result = JsonConvert.DeserializeObject<CheckVersionResult>(content);
return result;
}
catch (HttpRequestException)
{
form.showMessageBox("Je hebt een internetverbinding nodig om dit programma te kunnen gebruiken");
return null;
}
}
不幸的是，错误消息是用荷兰语编写的，所以你们大多数人都无法阅读完整的错误消息。 最重要的一行可能是stacktrace的第一行，它的英文翻译是：“ SocketException（0x80004005）：提供了无效的参数”。

该公司的PC正在运行由NET47REL1LAST构建的Windows 32位版本4.7.2117.0。所有功能都被管理员阻止，因此我无法检查有关系统信息的任何内容，而且很遗憾，我也无法在此计算机上安装任何内容...我的猜测是，问题与该问题有关.NET Framework版本，但我可能错了...
任何帮助将不胜感激！ 提前致谢！ Joeri。

.Net 4.0不支持异步等待升级到4.5或更高版本，并且可以正常工作。我相信您的本地PC在更高版本的.net上运行，这就是为什么该应用程序在您的个人PC上运行没有任何问题的原因
