C#進行Post請求（解決url過長的問題）

//實例代碼：

1.post請求

private string GetImageXY(string imgbyte)
{
string result3 = string.Empty;
try
{
string requestUri = "";//請求的url
HttpClient httpClient = new HttpClient();
//參數實例 p1=v1&p2=v2
string str = "imgbase64=" + imgbyte;
var content = new StringContent(str, Encoding.UTF8, "application/x-www-form-urlencoded");
HttpResponseMessage result = httpClient.PostAsync(requestUri, content).Result;
string result2 = result.Content.ReadAsStringAsync().Result;
result3 = result2;
}
catch (Exception ex)
{
result3 = "error";
}
return result3;
}
