[英]Migrating short vb6 code that uses WinHttp.WinHttpRequest to c# or vb.net
can someone please guide me how to convert that vb6 code to c# or visual basic.net. 有人可以指导我如何将vb6代码转换为c#或visual basic.net。 i have tried to to use the
System.Net.WebRequest()
class but with no success (everything i treys throws another exception so i think that adding my c# code will not be helpful). 我试图使用
System.Net.WebRequest()
类但没有成功(我的所有东西都引发了另一个异常,因此我认为添加我的C#代码将无济于事)。
this code works fine (i tested it with the vba editor). 这段代码可以正常工作(我使用vba编辑器对其进行了测试)。
clarification: I DONT EXPECT SOME TO DO MY JOB i just need to understand the equivilent methods of the first 11 rows in GetHTTPResponse()
function to System.Net.WebRequest()
class medhods , it will be enough and i will be able to handle it alone from that point. 澄清:我不希望做我的工作我只需要了解
System.Net.WebRequest()
类方法的GetHTTPResponse()
函数中前11行的等效方法,就足够了,我将能够处理从那一点开始。
thank you very much for your time and consideration. 非常感谢您的时间和考虑。

The best way to perform a web request in C# is using the HttpClient
, as long as you support .NET 4.5+. 只要您支持.NET 4.5+,在C#中执行Web请求的最佳方法就是使用
HttpClient
。 Here's a simple example: 这是一个简单的例子:
using (var client = new HttpClient())
{
var values = new Dictionary<string, string>
{
{ "username", username },
{ "password", password }
};
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var content = new FormUrlEncodedContent(values);
var response = await client.PostAsync(sURL, content);
if (response.IsSuccessStatusCode)
{
var response = await response.Content.ReadAsString();
// then repeat for the next request
}
}
Here is a good resource for learning about HttpClient. 这是学习HttpClient的好资源。
Be sure to mark your GetHTTPResponse method with the async
keyword. 确保使用
async
关键字标记您的GetHTTPResponse方法。
