WPF文本框和下拉框无法使用搜狐输入法输入的解决方案

可能是因为该代码没有设置输入法属性，导致无法使用搜狐输入法输入。可以尝试在创建文本框和下拉框时，设置输入法属性为搜狐输入法，例如：

var text = new TextBox()
{
    Margin = new Thickness(0, 5, 0, 5),
    FontSize = 17,
    Foreground = Brushes.Blue,
    VerticalAlignment = VerticalAlignment.Center,
    Width = 80,
    InputMethod.IsInputMethodEnabledProperty = true,
    InputMethod.InputMethodPreference = new InputMethod { PreferredImeState = InputMethodState.On }
};
Grid.SetRow(text, i);
Grid.SetColumn(text, j * 3 + 1);
grid.Children.Add(text);

同样的，在创建下拉框时也需要设置输入法属性。

示例代码：

Grid grid = new Grid();
grid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(70) });
grid.RowDefinitions.Add(new RowDefinition() { Height = GridLength.Auto });
grid.RowDefinitions.Add(new RowDefinition() { Height = GridLength.Auto });
grid.RowDefinitions.Add(new RowDefinition() { Height = GridLength.Auto });
grid.RowDefinitions.Add(new RowDefinition() { Height = GridLength.Auto });
grid.RowDefinitions.Add(new RowDefinition() {});
grid.ColumnDefinitions.Add(new ColumnDefinition());
grid.ColumnDefinitions.Add(new ColumnDefinition());
grid.ColumnDefinitions.Add(new ColumnDefinition());
grid.ColumnDefinitions.Add(new ColumnDefinition());
grid.ColumnDefinitions.Add(new ColumnDefinition());
grid.ColumnDefinitions.Add(new ColumnDefinition());
grid.ColumnDefinitions.Add(new ColumnDefinition());
grid.ColumnDefinitions.Add(new ColumnDefinition());
grid.ColumnDefinitions.Add(new ColumnDefinition());
grid.ColumnDefinitions.Add(new ColumnDefinition());
grid.ColumnDefinitions.Add(new ColumnDefinition());

// 创建TextBlock
TextBlock textBlock = new TextBlock()
{
    Text = '指标维护',
    HorizontalAlignment = HorizontalAlignment.Center,
    VerticalAlignment = VerticalAlignment.Center,
    FontSize = 25,
    Foreground = Brushes.Blue
};
Grid.SetRow(textBlock, 0);
Grid.SetColumn(textBlock, 0);
Grid.SetColumnSpan(textBlock, 12);
grid.Children.Add(textBlock);

string[] strName = { '   IL', 'ISO', 'DIR' };
for (int i = 1; i <= 3; i++)
{
    for (int j = 0; j < 4; j++)
    {
        var textTitle = new TextBlock()
        {
            Margin = new Thickness(20, 5, 0, 5),
            FontSize = 17,
            Foreground = Brushes.Blue,
            Text = strName[i - 1] + (j + 1).ToString() + '：',
            HorizontalAlignment = HorizontalAlignment.Center,
            VerticalAlignment = VerticalAlignment.Center
        };
        Grid.SetRow(textTitle, i);
        Grid.SetColumn(textTitle, j * 3);
grid.Children.Add(textTitle);

        var text = new TextBox()
        {
            Margin = new Thickness(0, 5, 0, 5),
            FontSize = 17,
            Foreground = Brushes.Blue,
            VerticalAlignment = VerticalAlignment.Center,
            Width = 80,
            InputMethod.IsInputMethodEnabledProperty = true,
            InputMethod.InputMethodPreference = new InputMethod { PreferredImeState = InputMethodState.On }
        };
        Grid.SetRow(text, i);
        Grid.SetColumn(text, j * 3 + 1);
grid.Children.Add(text);

        var textuit = new TextBlock()
        {
            Margin = new Thickness(0, 5, 0, 5),
            FontSize = 17,
            Foreground = Brushes.Blue,
            Text = 'nm',
            HorizontalAlignment = HorizontalAlignment.Center,
            VerticalAlignment = VerticalAlignment.Center
        };
        Grid.SetRow(textuit, i);
        Grid.SetColumn(textuit, j * 3 + 2);
grid.Children.Add(textuit);
    }
}
