Question

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文本框时遇到问题：

SpellCheck.SetIsEnabled(txtWhatever, true);

问题是我的txtWake类型System.Windows.Forms和该函数正在寻找的参数是System.Windows.Controls，简单转换失败。我也尝试制作这种类型的TextBox，但是......不能。有谁知道如何使用这个SpellCheck对象？（MSDN没那么有用......）

您必须使用WPF TextBox才能进行拼写检查。您可以使用ElementHost控件在Windows窗体表单中嵌入一个。它的工作方式与UserControl非常相似。这是一个可以直接从工具箱中删除的控件。首先，您需要Project + Add Reference并选择WindowsFormsIntegration，System.Design和WPF程序集PresentationCore，PresentationFramework和WindowsBase。

在项目中添加一个新类并粘贴下面显示的代码。编译。将SpellBox控件从工具箱顶部拖放到表单上。它支持TextChanged事件以及Multiline和WordWrap属性。 Font有一个令人烦恼的问题，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表单的Font设置为“Segoe UI”，这是WPF的默认设置。

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;
}

受欢迎的需求，这个代码的VB.NET版本避免了lambda：

Imports System
Imports System.ComponentModel
Imports System.ComponentModel.Design.Serialization
Imports System.Windows
Imports System.Windows.Controls
Imports System.Windows.Forms.Integration
Imports System.Windows.Forms.Design

    Public Sub New()
        box = New TextBox()
        MyBase.Child = box
        AddHandler box.TextChanged, AddressOf box_TextChanged
        box.SpellCheck.IsEnabled = True
        box.VerticalScrollBarVisibility = ScrollBarVisibility.Auto
        Me.Size = New System.Drawing.Size(100, 20)
    End Sub

    Private Sub box_TextChanged(ByVal sender As Object, ByVal e As EventArgs)
        OnTextChanged(EventArgs.Empty)

Answer 2

您是否尝试过在尝试拼写检查的实际TextBox上设置属性。例如

txtWhatever.SpellCheck.IsEnabled = true;

Answer 3

您正尝试在WinForms应用程序上使用为WPF设计的拼写检查组件。他们是不相容的。

如果要使用.NET提供的拼写检查，则必须使用WPF作为窗口小部件系统。

如果你想坚持使用WinForms，你需要一个第三方拼写检查组件。

Answer 4

可以看到基于WPF文本框的可用于客户端或服务器端的免费.NET拼写检查程序here。它将为您包装文本框，尽管您仍然需要将程序集包含到Presentation框架等。

我需要在winforms中为文本框添加背景颜色，以反映设计师中选择的颜色：

public override System.Drawing.Color BackColor
{
    get
    {
        if (box == null) { return Color.White; }
        System.Windows.Media.Brush br = box.Background;
        byte a = ((System.Windows.Media.SolidColorBrush)(br)).Color.A;
        byte g = ((System.Windows.Media.SolidColorBrush)(br)).Color.G;
        byte r = ((System.Windows.Media.SolidColorBrush)(br)).Color.R;
        byte b = ((System.Windows.Media.SolidColorBrush)(br)).Color.B;
        return System.Drawing.Color.FromArgb((int)a, (int)r, (int)g, (int)b);
    }
    set 
    {
        box.Background = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Color.FromArgb(value.A, value.R, value.G, value.B));
    }
}

如果您想启用 TextChanged 事件，请像这样编写代码。

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;
        box.TextChanged += new System.Windows.Controls.TextChangedEventHandler(SpellBox_TextChanged);
        this.Size = new System.Drawing.Size(100, 20);
    }

    [Browsable(true)]
    [Category("Action")]
    [Description("Invoked when Text Changes")]
    public new event EventHandler TextChanged;
    protected void SpellBox_TextChanged(object sender, EventArgs e)
    {        
        if (this.TextChanged!=null)
            this.TextChanged(this, e);
    }
    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)]
