尝试使用C＃SpellCheck类

大佬教程收集整理的这篇文章主要介绍了尝试使用C＃SpellCheck类，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

如何解决尝试使用C＃Spellcheck类？

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windows窗体表单中。它的工作原理与UserControl非常相似。这是一个您可以直接从工具箱中放下的控件。首先，您需要Project + Add Reference，然后选择windowsFormsIntegration，System.Design和WPF程序集PresentationCore，PresentationFramework和windowsBase。

将新类添加到您的项目中，然后粘贴以下代码。编译。将SpellBox控件从工具箱的顶部拖放到窗体上。它支持TextChanged事件以及Multiline和WorDWrap属性。字体存在困扰，没有简单的方法可以将WF字体映射到WPF字体属性。最简单的解决方法是将窗体的Font设置为WPF的默认“ Segoe UI”。

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;
}

根据普遍的需求，此代码的VB.NET版本避免使用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

<Designer(GetType(ControlDesigner))> _
Class SpellBox
    inherits ElementHost

    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)
    End Sub

    Public OverrIDes Property Text() As String
        Get
            Return Box.Text
        End Get
        Set(ByVal value As String)
            Box.Text = value
        End Set
    End Property

    <DefaultValue(false)> _
    Public Property Multiline() As @R_772_8487@an
        Get
            Return Box.AcceptsReturn
        End Get
        Set(ByVal value As @R_772_8487@an)
            Box.AcceptsReturn = value
        End Set
    End Property

    <DefaultValue(false)> _
    Public Property WorDWrap() As @R_772_8487@an
        Get
            Return Box.textwrapPing <> textwrapPing.nowrap
        End Get
        Set(ByVal value As @R_772_8487@an)
            If value Then
                Box.textwrapPing = textwrapPing.Wrap
            Else
                Box.textwrapPing = textwrapPing.nowrap
            End If
        End Set
    End Property

    <DesignerserializationVisibility(DesignerserializationVisibility.HIDden)> _
    Public Shadows Property Child() As System.windowS.UIElement
        Get
            Return MyBase.Child
        End Get
        Set(ByVal value As System.windowS.UIElement)
            '' Do nothing to solve a problem with the serializer !!
        End Set
    End Property
    Private Box As TextBox
End Class

解决方法

Spellcheck.SetIsEnabled(txtwhatever,truE);
