篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了c#新建WPF后没有设计器，但是程序可以运行？相关的知识，希望对你有一定的参考价值。
vs2019新建WPF后，无法查看设计器，窗口提示如下，程序是可以运行的，但是没有设计器是没办法添加控件啊
重新生成解决方案
重启VS
应用程序使用统计信息 – .NET CORE(C#) WPF界面设计
关键功能点
抽屉式菜单
圆形进度条
Demo演示：
1. 新建项目
使用 VS 2019 的 .NET Core 3.1 WPF 项目模板，创建名为 “MobileAppUsageDashboardCore” 的项目，NuGet 引入 MaterialDesign 的两个库 MaterialDesignThemes 和 MaterialDesignColors，整个项目工程文件如下：
<Project Sdk="Microsoft.NET.Sdk.WindowsDesktop">
<PropertyGroup>
<OutputType>WinExe</OutputType>
<TargetFramework>netcoreapp3.1</TargetFramework>
<UseWPF>true</UseWPF>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="MaterialDesignColors" Version="1.2.2" />
<PackageReference Include="MaterialDesignThemes" Version="3.0.1" />
</ItemGroup>
</Project>
2.抽屉式菜单
前面发过不少抽屉式菜单的Demo文章，套路都是一个竖直菜单隐藏在界面左边边界之外，左边边界留一个菜单按钮，点击该按钮呼出竖直菜单，即达到抽屉式菜单效果。
本文介绍的抽屉式菜单也不外如是,VS设计界面见上图，使用的MD控件的DrawerHost.LeftDrawerContent组件，换一种方式实现，下面是抽屉菜单布局代码：
<materialDesign:DrawerHost.LeftDrawerContent>
<StackPanel Orientation="Vertical">
<StackPanel Margin="10" VerticalAlignment="Top" Orientation="Horizontal">
<TextBlock
VerticalAlignment="Center"
Margin="0,0,10,0">Dashboard</TextBlock>
<Button Style="{StaticResource MaterialDesignFlatButton}"
Command="{x:Static materialDesign:DrawerHost.CloseDrawerCommand}"
>
<materialDesign:PackIcon Kind="HamburgerMenuBack"></materialDesign:PackIcon>
</Button>
</StackPanel>
<StackPanel Orientation="Vertical">
<Button Style="{StaticResource MaterialDesignFlatButton}" Click="todayBtnClicked">今天</Button>
<Button Style="{StaticResource MaterialDesignFlatButton}" Click="weekBtnClicked">本周</Button>
<Button Style="{StaticResource MaterialDesignFlatButton}" Click="monthBtnClicked">本月</Button>
</StackPanel>
</StackPanel>
</materialDesign:DrawerHost.LeftDrawerContent>
跟随菜单隐藏的还有一个菜单关闭按钮，见上面代码中的第一个按钮，点击按钮触发 “DrawerHost.CloseDrawerCommand” 命令可关闭抽屉式菜单。
下面的是窗体边界之内的菜单按钮，点击则展开抽屉式菜单，触发的命令是“DrawerHost.OpenDrawerCommand”：
<Button Style="{StaticResource MaterialDesignFlatButton}" Command="{x:Static materialDesign:DrawerHost.OpenDrawerCommand}"
HorizontalAlignment="Left"
VerticalAlignment="Top"
>
<materialDesign:PackIcon Kind="HamburgerMenu"></materialDesign:PackIcon>
</Button>
3.圆形进度条
使用MD控件库实现圆形进度条，效果如下：
圆形进度条代码如下，使用的还是 ProgressBar 控件，样式使用了MD控件库的“MaterialDesignCircularProgressBar” 样式，组件加载时(Loaded事件)，使用了双精度动画：
<ProgressBar Height="100"
Width="100"
Value="40" Foreground="#FF68E843"
x:Name="firstProgress"
>
<ProgressBar.Style>
<Style TargetType="ProgressBar" BasedOn="{StaticResource MaterialDesignCircularProgressBar}">
<Style.Triggers>
<EventTrigger RoutedEvent="Loaded">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="Value" From="0" To="40"
Duration="0:0:0.5"></DoubleAnimation>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Style.Triggers>
</Style>
</ProgressBar.Style>
</ProgressBar>
4. Demo源码
整个Demo也不难，除了上面两个小功能单独简单说说外，其他的就是一般的布局代码了，主界面XAML代码如下：

5. 主界面后台代码
代码不多，比较简单，源码如下：
using System;
using System.Windows;
using System.Windows.Input;
namespace MobileAppUsageDashboardCore
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void todayBtnClicked(object sender, RoutedEventArgs e)
{
mainDrawer.IsLeftDrawerOpen = false;
todayRadio.IsChecked = true;
monthRadio.IsChecked = false;
weekRadio.IsChecked = false;
}
private void weekBtnClicked(object sender, RoutedEventArgs e)
{
mainDrawer.IsLeftDrawerOpen = false;
todayRadio.IsChecked = false;
weekRadio.IsChecked = true;
monthRadio.IsChecked = false;
}
private void monthBtnClicked(object sender, RoutedEventArgs e)
{
mainDrawer.IsLeftDrawerOpen = false;
todayRadio.IsChecked = false;
weekRadio.IsChecked = false;
monthRadio.IsChecked = true;
}
private void dragME(object sender, MouseButtonEventArgs e)
{
try
{
DragMove();
}
catch (Exception)
{
//throw;
}
}
}
}
