试图使用C＃拼写检查类 [英] Trying to use the C# SpellCheck class

问题描述

我试图使用拼写检查类C＃提供了（在presentationFramework.dll）。 但是，我遇到问题，试图拼写绑定到我的文本框时：

I am trying to use the SpellCheck class C# provides (in PresentationFramework.dll). But, I am experiencing problems when trying to bind the spelling to my textbox:

SpellCheck.SetIsEnabled(txtWhatever, true);

的问题是，我的txtWhatever是类型System.Windows.Forms的与该功能正在寻找的参数是System.Windows.Controls的，而简单的转换失败。 我也试图让我这种类型的文本框，但......不能。 有谁知道如何使用这个拼写检查的对象？ （MSDN是不是有帮助...）

The problem is that my txtWhatever is of type System.Windows.Forms and the parameter this function is looking for is System.Windows.Controls, and simple converting failed. I also tried to make my TextBox of this type, but... couldn't. Does anyone know how to use this SpellCheck object? (MSDN wasn't that helpful...)

感谢

推荐答案

您必须使用WPF文本框进行拼写检查工作。您可以嵌入之一，与ElementHost控件在Windows窗体形式。它的工作原理类似于用户控件pretty的。这里有一个控件，您可以直接从工具箱下降。要开始，你需要项目+添加引用和WindowsFormsIntegration程序选择，System.Design和WPF组件presentationCore，presentationFramework和WindowsBase。

You have to use a WPF TextBox to make spell checking work. You can embed one in a Windows Forms form with the ElementHost control. It works pretty similar to a UserControl. Here's a control that you can drop straight from the toolbox. To get started, you need Project + Add Reference and select WindowsFormsIntegration, System.Design and the WPF assemblies PresentationCore, PresentationFramework and WindowsBase.

添加一个新类到您的项目并粘贴下面所示的code。编译。从工具箱顶部的SpellBox控件到窗体。它支持TextChanged事件和多行和自动换行属性。有一个挥之不去的问题与字体，有没有简单的方法来一个WF字体映射到WPF字体属性。最简单的解决方法是设置窗体的字体为的Segoe UI，默认为WPF。

Add a new class to your project and paste the code shown below. Compile. Drop the SpellBox control from the top of the toolbox onto a form. It supports the TextChanged event and the Multiline and WordWrap properties. There's a nagging problem with the Font, there is no easy way to map a WF Font to the WPF font properties. The easiest workaround for that is to set the form's Font to "Segoe UI", the default for WPF.

using System;
using System.ComponentModel;
using System.ComponentModel.Design.Serialization;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Forms.Integration;
using System.Windows.Forms.Design;

[Designer(typeof(ControlDesigner))]
//[DesignerSerializer("System.Windows.Forms.Design.ControlCodeDomSerializer, System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a", "System.ComponentModel.Design.Serialization.CodeDomSerializer, System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")]
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; }
    }
    [DefaultValue(false)]
    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 {
        get { return base.Child; }
        set { /* Do nothing to solve a problem with the serializer !! */ }
    }
    private TextBox box;
}

应广大用户要求，一个VB.NET的版本，这code，避免拉姆达：
