namespace WindowsFormsApplication2
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            this.textBox1.Text = GetPinyin("你是我的小苹果");//获取全拼

            this.textBox2.Text = GetFirstPinyin("你是我的小苹果");//获取首字母
        }

        /// <summary>
        /// 汉字转化为拼音
        /// </summary>
        /// <param name="str">汉字</param>
        /// <returns>全拼</returns>
        public static string GetPinyin(string str)
        {
            string r = string.Empty;
            foreach (char obj in str)
            {
                try
                {
                    ChineseChar chineseChar = new ChineseChar(obj);
                    string t = chineseChar.Pinyins[0].ToString();
                    r += t.Substring(0, t.Length - 1);
                }
                catch
                {
                    r += obj.ToString();
                }
            }
            return r;
        }

        /// <summary>
        /// 汉字转化为拼音首字母
        /// </summary>
        /// <param name="str">汉字</param>
        /// <returns>首字母</returns>
        public static string GetFirstPinyin(string str)
        {
            string r = string.Empty;
            foreach (char obj in str)
            {
                try
                {
                    ChineseChar chineseChar = new ChineseChar(obj);
                    string t = chineseChar.Pinyins[0].ToString();
                    r += t.Substring(0, 1);
                }
                catch
                {
                    r += obj.ToString();
                }
            }
            return r;
        }
    }

}

效果：
