正在尝试使用C# SpellCheck类
我正在尝试使用C#提供的SpellCheck类(在PresentationFramework.dll中)。但是，我在尝试将拼写绑定到我的文本框时遇到了问题：
SpellCheck.SetIsEnabled(txtWhatever, true);问题是我的txtWhatever是System.Windows.Forms类型，这个函数要查找的参数是System.Windows.Controls，简单的转换失败了。我也试过做这种类型的TextBox，但是...不能。有人知道如何使用此SpellCheck对象吗？(MSDN没有那么有帮助...)
谢谢

您必须使用WPF TextBox才能进行拼写检查。您可以使用ElementHost控件将其嵌入到Windows窗体窗体中。它的工作原理与UserControl非常相似。这是一个可以直接从工具箱中拖放的控件。要开始，您需要项目+添加引用，并选择WindowsFormsIntegration，System.Design和WPF程序集PresentationCore，PresentationFramework和WindowsBase。
向您的项目添加一个新类，并粘贴如下所示的代码。编译。将SpellBox控件从工具箱顶部拖放到窗体上。它支持TextChanged事件以及Multiline和WordWrap属性。字体有一个令人困扰的问题，没有简单的方法将WF字体映射到WPF字体属性。最简单的解决方法是将窗体的字体设置为"Segoe UI"，这是WPF的默认设置。

class SpellBox : ElementHost {
public SpellBox() {
box = new TextBox();
base.Child = box;
box.TextChanged += (s, e) => OnTextChanged(EventArgs.Empty);
box.SpellCheck.IsEnabled = true;
box.VerticalScrollBarVisibility = ScrollBarVisibility.Auto;
this.Size = new System.Drawing.Size(100, 20);
}
public override string Text {
get { return box.Text; }
set { box.Text = value; }
}
[DefaultValue(false)]
public bool Multiline {
get { return box.AcceptsReturn; }
set { box.AcceptsReturn = value; }

public bool WordWrap {
get { return box.TextWrapping != TextWrapping.NoWrap; }
set { box.TextWrapping = value ? TextWrapping.Wrap : TextWrapping.NoWrap; }

[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public new System.Windows.UIElement Child {

您是否尝试过在您尝试拼写检查的实际TextBox上设置属性。例如：
txtWhatever.SpellCheck.IsEnabled = true;Stack Overflow用户

您正尝试在WinForms应用程序上使用为WPF设计的拼写检查组件。它们是不兼容的。
如果你想使用.NET提供的拼写检查，你必须使用WPF作为你的窗口小部件系统。
如果你想继续使用WinForms，你需要一个第三方的拼写检查组件。
