我应该怎么称呼这种方法？ [英] How should I call this method?

问题描述

我正在尝试使用whatsApp api创建一个简单的消息传递应用程序。问题是我无法调用请求注册码的方法。我查阅了文档，我无法弄清楚我应该发送什么参数。



这就是给我带来问题的一条线。

I am trying to make an simple messaging app using whatsApp api. The problem is that i can't call the method for requesting the registration code. I've looked up on documentation and i can't figure out what parameters i should send in.

This is the line that is giving me problems.

WhatsAppApi.Register.WhatsRegisterV2.RequestCode(txtPhoneNumber.Text, out password, "sms")

它说我必须提供2个参数。

It saids that i must give 2 out parameters.

Error	1	The best overloaded method match for 'WhatsAppApi.Register.WhatsRegisterV2.RequestCode(string, out string, out string, string, string)' has some invalid arguments

你能帮助我吗？

What I have tried:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace LamaChat
{
    public partial class Register : Form
    {

        string password;

        public Register()
        {
            InitializeComponent();
        }

        private void label4_Click(object sender, EventArgs e)
        {

        }

        private void btnRequest_Click(object sender, EventArgs e)
        {
            if(string.IsNullOrEmpty(txtPhoneNumber.Text))
            {
                MessageBox.Show("Please enter your phone number.", "Message", MessageBoxButtons.OK, MessageBoxIcon.Information);
                txtPhoneNumber.Focus();
                return;
            }

            if (string.IsNullOrEmpty(txtFullName.Text))
            {
                MessageBox.Show("Please enter your phone name.", "Message", MessageBoxButtons.OK, MessageBoxIcon.Information);
                txtFullName.Focus();
                return;
            }

            if(WhatsAppApi.Register.WhatsRegisterV2.RequestCode(txtPhoneNumber.Text, out password, "sms"))
            {

            }

        }

        private void btnConfirm_Click(object sender, EventArgs e)
        {

        }
    }
}

推荐答案

查看错误：

Look at the error:

The best overloaded method match for 'WhatsAppApi.Register.WhatsRegisterV2.RequestCode(string, out string, out string, string, string)' has some invalid arguments

这就是说最好的匹配是一个带字符串的方法，两个输出字符串和另外两个字符串。

你这样称呼它：

That says that the best match is a method that takes a string, two output strings, and two other strings.
You are calling it thus:

WhatsAppApi.Register.WhatsRegisterV2.RequestCode(txtPhoneNumber.Text, out password, "sms")

提供一个字符串，一个输出字符串和最终字符串。

文档中有一个与该签名匹配的重载：

Which provides a string, one output string, and a final string.
There is an overload in the documentation which matches that signature:

public static bool RequestCode(string phoneNumber, out string password, string method = "sms", string id = null)

所以我首先检查你是否加载了正确的API版本并且你也是引用正确的版本。

So I'd start by checking you have the right version of the API loaded and that you are also referencing the right version.
