winform微信支付

WinForm微信支付可以通过生成订单展示二维码的方式实现。你可以使用轮询的方式检查支付结果，直到支付成功为止。在WinForm中，你可以创建一个线程来进行轮询查询，查询订单支付状态。可以参考以下代码实现查询功能：

private void Query()
{
Thread thread = new Thread(LoopQuery);
thread.IsBackground = true;
thread.Start();
}

private void LoopQuery(object msg)
{
int i = 0;
WxPayData Querydata = new WxPayData();
Querydata.SetValue("out_trade_no", textBox_id.Text);

for (i = 0; i < 3; i++)
{
Thread.Sleep(5000); //每隔5s查询一次
WxPayData result = WxPayApi.OrderQuery(Querydata, 6);

var code = result.GetValue("return_code").ToString();
if (code == "SUCCESS")
{
var state = result.GetValue("trade_state").ToString();
if (state == "SUCCESS")
break;
}
}

if (i >= 3)
MessageBox.Show("还未成功付款哦");
else
MessageBox.Show("成功付款");
}
请确保在代码中引用了相关的第三方库和配置文件，并进行适当的配置。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
