C#上位机与欧姆龙PLC的通信10----开发专用的通讯工具软件(WPF版)-编程知识

1、介绍

上节开发了一个winform版的通讯测试工具，这节再搞个wpf版的，wpf是什么？请自行百度，也可以看前面的博客，WPF真入门教程，wpf的界面效果是比winform漂亮，因为wpf使用了web项目中的css样式来美化界面，在这个例子中用到wpf的控件，资源样式，命令绑定等，采用的是mvvm的渲染模式，界面如图：

前面的winform界面：

2、开工干

2.1 创建wpf项目

2.2 创建目录及PLC模型类对象

2.3 创建自定义的消息弹窗

MsgBoxWindow.xaml代码

MsgBoxWindow.xaml.cs代码（这是页面MsgBoxWindow.xaml的后台逻辑代码）

}

2.4 添加之前的通讯库dll文件，并引用到项目中

2.5 添加目录及命令类RelayCommand

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Input;namespace OmronFinsWPFApp.Common
{/// <summary>/// 命令实现类/// </summary>public class RelayCommand : ICommand{public event EventHandler CanExecuteChanged;/// <summary>/// 要执行的操作/// </summary>private Action<object> executeActions;/// <summary>/// 是否可以执行的委托/// </summary>private Func<object, bool> canExecuteFunc;/// <summary>/// 构造函数 无参构造/// </summary>public RelayCommand() { }/// <summary>/// 通过执行的委托构造/// </summary>/// <param name="execute"></param>public RelayCommand(Action<object> execute) : this(execute, null){}/// <summary>/// 通过执行的操作与是否可执行的委托/// </summary>/// <param name="execute">要执行的操作</param>/// <param name="canExecute">是否可以被执行</param>public RelayCommand(Action<object> execute, Func<object, bool> canExecute){this.executeActions = execute;this.canExecuteFunc = canExecute;}/// <summary>/// 命令是否可以执行/// </summary>/// <param name="parameter"></param>/// <returns></returns>public bool CanExecute(object parameter){if (canExecuteFunc != null)return this.canExecuteFunc(parameter);elsereturn true;}/// <summary>/// 要执行的操作/// </summary>/// <param name="parameter"></param>public void Execute(object parameter){if (executeActions == null)return;this.executeActions(parameter);}/// <summary>/// 执行CanExecuteChanged事件/// </summary>public void OnCanExecuteChanged(){this.CanExecuteChanged?.Invoke(this, new EventArgs());}}
}

2.6 添加视图模型类对象

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Linq;
using System.Runtime.CompilerServices;
using System.Text;
using System.Threading.Tasks;
using static OmronFinsWPFApp.MsgBoxWindow;namespace OmronFinsWPFApp.ViewModel
{/// <summary>/// 视图模型基类/// </summary>public class ViewModelBase : INotifyPropertyChanged{/// <summary>/// 属性值发生更改时触发/// </summary>public event PropertyChangedEventHandler PropertyChanged;/// <summary>/// 执行更改/// C#5.0中的新特性CallerMemberName/// </summary>/// <param name="propertyName"></param>protected void OnPropertyChanged([CallerMemberName] string propertyName = ""){if (PropertyChanged != null){PropertyChanged.Invoke(this, new PropertyChangedEventArgs(propertyName));}}/// <summary>/// 成功消息提示/// </summary>/// <param name="message"></param>/// <param name="title"></param>/// <param name="buttons"></param>public void ShowMessage(string message, string title = "提示", CustomMessageBoxButton buttons = CustomMessageBoxButton.OK){Show(message, title, buttons, CustomMessageBoxIcon.Infomation);}/// <summary>/// 错误消息框/// </summary>/// <param name="message"></param>/// <param name="title"></param>/// <param name="buttons"></param>public void ShowError(string message, string title = "错误", CustomMessageBoxButton buttons = CustomMessageBoxButton.OK){Show(message, title, buttons, CustomMessageBoxIcon.Error);}/// <summary>/// 询问消息框/// </summary>/// <param name="message"></param>/// <param name="title"></param>/// <param name="buttons"></param>/// <returns></returns>public CustomMessageBoxResult ShowQuestion(string message, string title = "询问", CustomMessageBoxButton buttons = CustomMessageBoxButton.OKCancel){return Show(message, title, buttons, CustomMessageBoxIcon.Question);}}
}

}

2.7 主界面样式

首先添加资源文件

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"><!--定义通用的按钮样式--><Style TargetType="{x:Type Button}" x:Key="btnBaseStyle"><Setter Property="Height" Value="22"/><Setter Property="Width" Value="60"/><Setter Property="FontFamily" Value="微软雅黑"/><Setter Property="Margin" Value="3,0"/><Setter Property="FontSize" Value="16"/><Setter Property="FontWeight" Value="Bold"/><Setter Property="Foreground"  Value="Blue"/></Style><!--TextBox默认样式--><Style TargetType="{x:Type TextBox}" x:Key="txtTextBoxStyle"><Setter Property="Width" Value="150"/><Setter Property="Height" Value="25"/><Setter Property="BorderBrush" Value="#FF105190"/><Setter Property="BorderThickness" Value="1"/><Setter Property="Margin" Value="2,0"/><Setter Property="VerticalContentAlignment" Value="Center"/><Setter Property="Background"><Setter.Value><LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1"><GradientStop Color="White" Offset="0"/><GradientStop Color="#FFE4E4E4" Offset="1"/></LinearGradientBrush></Setter.Value></Setter></Style><!--TextBlock默认样式--><Style TargetType="{x:Type TextBlock}" x:Key="txtTextBlockStyle"><Setter Property="Margin" Value="1"/><Setter Property="Height" Value="15"/></Style><!--页面下拉框样式--><LinearGradientBrush x:Key="ComboBox.Static.Background" EndPoint="0,1" StartPoint="0,0"><GradientStop Color="White" Offset="0"/><GradientStop Color="#FFE4E4E4" Offset="1"/></LinearGradientBrush><SolidColorBrush x:Key="ComboBox.Static.Border" Color="#FF105190"/><!--combox默认样式--><Style x:Key="cboStyle" TargetType="{x:Type ComboBox}"><Setter Property="Background" Value="{StaticResource ComboBox.Static.Background}"/><Setter Property="BorderBrush" Value="{StaticResource ComboBox.Static.Border}"/><Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.WindowTextBrushKey}}"/><Setter Property="Width" Value="150"/><Setter Property="Height" Value="25"/><Setter Property="BorderThickness" Value="1"/><Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Auto"/><Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto"/><Setter Property="Padding" Value="6,3,5,3"/><Setter Property="ScrollViewer.CanContentScroll" Value="true"/><Setter Property="ScrollViewer.PanningMode" Value="Both"/><Setter Property="Stylus.IsFlicksEnabled" Value="False"/></Style>
</ResourceDictionary>

使用资源文件
