C# 切换输入法

comboBox1获取系统安装的所有拼音输入法，根据选择控制当前输入法，目前的做法会导致当前输入法与实际选择的不一致，不知道哪位能帮忙提出修改办法，感激不尽！
private void Form1_Load(object sender, EventArgs e)
{
InputLanguageCollection ilc = InputLanguage.InstalledInputLanguages;//获取系统已安装输入法

foreach (InputLanguage il in ilc )//将系统输入法添加到下拉菜单中
{
if(il.LayoutName.Contains("拼音"))
comboBox1.Items.Add(il.LayoutName);
}
comboBox1.SelectedIndex = InputLanguage.InstalledInputLanguages.IndexOf(InputLanguage.CurrentInputLanguage); //当前输入法
}
//根据下拉菜单的变化，切换系统输入法,并在文本框显示输入法名字
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
InputLanguage il = InputLanguage.InstalledInputLanguages[comboBox1.SelectedIndex];
InputLanguage.CurrentInputLanguage = il;
this.richTextBox1.Text = il.LayoutName;
}

Answer 1

我用你的代码试了,是好使的.

Answer 2

因为comboBox你做了筛选，所以comboBox的id和 InputLanguage的id是对不上的
你把后面的改成这样试试

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
InputLanguageCollection ilc = InputLanguage.InstalledInputLanguages;
foreach (InputLanguage il in ilc)
{
if (il.LayoutName.Contains(comboBox1.Text))
{
InputLanguage.CurrentInputLanguage = il;
this.richTextBox1.Text = il.LayoutName;
}
}

        void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
        //用SelectedItem 属性，你那个SelectedIndex会有问题
            InputLanguage a = this.comboBox1.SelectedItem as InputLanguage;
            if (a != null)
            {
                InputLanguage.CurrentInputLanguage = a;
            }
        }
