    {
        // 
        // TODO: 在此处添加构造函数逻辑 
        // 
    }    //设定当前Ime,使用方法Ime.SetImeName("中文 (简体) - 拼音加加");

LZ只要在GOOGLE中输入"C#控制输入法"就能找到答案

Answer 3

private void button1_Click(object sender, EventArgs e)
{
            InputLanguage il = GetDesiredInputLanguage("逍遥笔 4.0 版");
            if (il == null)
            {
                InputLanguage.CurrentInputLanguage = InputLanguage.DefaultInputLanguage;
                MessageBox.Show("未能找到");
            }
            textBox1.Select();
            InputLanguage.CurrentInputLanguage = il;
            
}
public static InputLanguage GetDesiredInputLanguage(string layoutName)
{
            InputLanguageCollection ilc = InputLanguage.InstalledInputLanguages;            foreach (InputLanguage il in ilc)
            {
                if (il.LayoutName == layoutName)
                    return il;
            }
            return null;
}

Answer 4

请问楼上的：
if (il.LayoutName == layoutName)   这句中的字符串是怎么比较的，就算看起来一样怎么还是不执行下面的这一句： return il; 
 
谢谢！！！！
