【问题描述】：

好的，所以我的项目正在构建为 ClassLibrary，我想要发生的是当我单击在 ExternalChat.SettingsWindow 类中调用函数的 CoreAuthKeyTestButton 时。请记住，CoreAuthKeyTestButton_Click 函数是由 Visual Studio 自动生成的，我只是输入了一行代码来输出它正在工作。

我正在制作的程序是另一个应用程序的插件，没关系，但想指出这一点。

Visual Studio 说这段代码很好。我构建它时没有错误。但是，当我加载插件时，出现此错误：

SettingsWindow.xaml(41,92) : error CS1061: 'SettingsWindow' does not contain a definition for 'CoreAuthKeyTestButton_Click' and no extension method 'CoreAuthKeyTestButton_Click' accepting a first argument of type 'SettingsWindow' could be found (are you missing a using directive or an assembly reference?)

这是 SettingsWindow.xaml

                    <TextBox x:Name="CoreAuthKeyInput" HorizontalAlignment="Left" Height="23" TextWrapping="Wrap" VerticalAlignment="Top" Width="400" Margin="93,1,0,0" Text="{Binding Path=CoreAuthKey}"/>

                </Grid>
            </TabItem>
        </TabControl>
    </Grid>
</Controls:MetroWindow>

这是 SettingsWindow.xaml.cs 文件：

using System;
using System.Linq;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Threading;
using MahApps.Metro;
using MahApps.Metro.Controls;
using Buddy.Overlay.Commands;
using System.Windows.Input;
using ff14bot.Helpers;

namespace ExternalChat
{
    public partial class SettingsWindow
    {
        public static string CoreAuthKey { get; set; }
        public static string CoreAuthKeyTest { get; set; }

        public SettingsWindow()
        {
            InitializeComponent();
        }

        protected void CoreAuthKeyTestButton_Click(object sender, RoutedEventArgs e)
        {
            Logging.Write("Save Core Auth Key Button Click Called");
        }
    }
}

任何帮助将不胜感激，我无法弄清楚我做错了什么，我认为这是我的 xaml 文件中的问题，但我无法找出它是什么。

标签： c# wpf xaml mahapps.metro

【解决方案1】：

 using MahApps.Metro.Controls;
 //
 public partial class MainWindow : MetroWindow

你会的

 public partial class SettingsWindow : MetroWindow

【讨论】：

将其更改为公共部分类 SettingsWindow 后仍然相同的错误：MetroWindow.

【解决方案2】：

我找到了解决办法！

本专题说明：https://stackoverflow.com/a/25110084/5377206

在我的具体实例中，我将按钮更改为

<Button Name="CoreAuthKeyTestButton" Content="Save &amp; Test Key" HorizontalAlignment="Left" VerticalAlignment="Top" Width="100" Margin="492,1,0,0" BorderThickness="1" Height="26" />

并将我的 SettingsWindow.xaml.cs 更改为：

public SettingsWindow()
    {
        InitializeComponent();
        CoreAuthKeyTestButton.Click += (s, e) => { CoreAuthKeyTestButtonClickAction(); };
    }

    private void CoreAuthKeyTestButtonClickAction()
    {
        Logging.Write("Save Core Auth Key Button Click Called");
    }

希望这对遇到问题的人有所帮助。
