<h3>示例代码</h3>
<p>以下是调用支付下单接口的基本示例：</p>
<p>```c#
// 1. 集合数据<br />
var requestData = new Dictionary<string, object>();
requestData.Add("AppID", "a5d3dd2f4c95db76");
requestData.Add("MerchantDetailedID", "3fa85f64-5717-4562-b3fc-2c963f66afa6");
requestData.Add("MerchantOrderNo", "T1999123456");
//签名
var sign = toSignHandle(requestData,AppSecret);
requestData.Add("Sign",sign);</p>
<pre><code> // 2. 发送请求
var requestUrl = &quot;http://merchant.sy1999.com//api/services/app/overseasopenapi/checkorder&quot;;
httpClient.ContentType = &quot;application/json&quot;;
var response = await httpClient.PostAsync(requestUrl,jsonData(requestData)); </code></pre>
<p>`
// 3. 获取响应<br />
var result = await response.Content.ReadAsStringAsync();<br />
Console.log(result); // { result.code,result.msg,result.data}; </p>
