我必须将旧经典 ASP 站点的一些逻辑转换为 asp.net 项目。我无法理解一些负责发布数据的功能。

这是经典 ASP 中的函数：

<%Function PostHTTP(strURL, strBody, strErrTemplate)
ON ERROR RESUME NEXT
Dim objHTTP, strResult

  Set objHTTP = Server.CreateObject("Msxml2.ServerXMLHTTP.3.0")

  If Err.Number <> 0 Then
    strResult = Replace(strErrTemplate, "%1", Err.Number)
    strResult = Replace(strResult, "%2", Err.Description)
    strResult = Replace(strResult, "%3", "Init::" & Err.Source)
    Set objHTTP = Nothing
    PostHTTP = strstrResult
    Exit Function
  End If

  With objHTTP
    .Open "POST", strURL, False
    .setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
    .setTimeouts 30000, 30000, 60000, 240000
    .send strBody

    If Err.Number <> 0 Then
      strResult = Replace(strErrTemplate, "%1", Err.Number)
      strResult = Replace(strResult, "%2", Err.Description)
      strResult = Replace(strResult, "%3", "Post::" & Err.Source)
    Else
      strResult = .responseText
    End If
  End With

' Response.Write "strResult: " & strResult
'Response.End


  If Err.Number > 0 Then
    strResult = Replace(strErrTemplate, "%1", Err.Number)
    strResult = Replace(strResult, "%2", Err.Description)
    strResult = Replace(strResult, "%3", Err.Source)
  ElseIf Len(strResult) = 0 Then
    strResult = Replace(strErrTemplate, "%1", 2000)
    strResult = Replace(strResult, "%2", "No response received from remote server.")
    strResult = Replace(strResult, "%3", "PostHTTP")
  End If

  PostHTTP = strResult
  Set objHTTP = Nothing
End Function

这在 asp.net 中会是什么样子？

ps：我已经尝试过自己的发布功能，但显然遗漏了一些东西，因为我的不起作用。

如果您使用WebClient类，POST 的主要任务将非常简单。例如，

// Form URL and POST-DATA
...
using (WebClient wc = new WebClient())
{
    wc.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
    string strResult = wc.UploadString(strURL, strBody);
}
...

对于更精细的控制，您可以使用WebRequest类。

编辑：这是示例代码，WebRequest因为您似乎需要指定无法使用的超时值WebClient

var request = WebRequest.Create(strUrl);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.Timeout = 240000; // set timeout
using (var writer = new StreamWriter(request.GetRequestStream()))
{
    // write to the body of the POST request
    writer.Write(strBody);
}
