强大的微软Microsoft Translator翻译接口

一、前言

当我们需要对日文、韩文等语言转换中文字符的时候，就用到了微软提供的翻译接口。

二、实现流程

1.首先注册一个账号 https://datamarket.azure.com/account

2.账户信息填写，注意国家/地区一定不要选择简体中文，以免后面找不到免费的功能，有些国家会有功能限制。

3.然后点击左侧的开发人员，注册一个应用程序

4.然后搜索Microsoft Translator，并点击进去，可以选择套餐，免费的话每个月只能转换两百万个字符，缴费就能选择更高级别套餐

5.现在我注册免费的，注册成功后，在我的账户-》我的数据里面可以看到

三、代码实现

        private void button3_Click(object sender, EventArgs e)
        {
            string errorCode;
            richTextBox1.Text = Biyabi.Common.MicrosoftTranslator.TranslateString(textBox1.Text, "ja", "zh-CHS", out errorCode);
            textBox2.Text = errorCode;
