我的DLL中没有PayResult这个类 需要自己去写
using System;
using System.Collections.Generic;
using System.Text;
using Android.Text;
namespace AlipayDemo
{
public class PayResult
{
private String resultStatus;
private String result;
private String memo;
public PayResult(String rawResult)
{
if (TextUtils.IsEmpty(rawResult))
return;
String[] resultParams = rawResult.Split(';');
foreach (String resultParam in resultParams)
{
if (resultParam.StartsWith("resultStatus"))
{
resultStatus = gatValue(resultParam, "resultStatus");
}
if (resultParam.StartsWith("result"))
{
result = gatValue(resultParam, "result");
}
if (resultParam.StartsWith("memo"))
{
memo = gatValue(resultParam, "memo");
}
}
}
public override string ToString()
{
return "resultStatus={" + resultStatus + "};memo={" + memo + "};result={" + result + "}";
}
private String gatValue(String content, String key)
{
String prefix = key + "={";
return content.Substring(content.IndexOf(prefix) + prefix.Length,
content.LastIndexOf("}"));
}
public String getResultStatus()
{
return resultStatus;
}
public String getMemo()
{
return memo;
}
public String getResult()
{
return result;
}
}
}
至此配置好支付宝那边网关公钥私钥问题就可以运行啦
