如何在Visual Studio Designer中获取我可以选择的所有颜色的列表( System.Windows.Media.Colors ,但那不是收藏)并把它们放进我自己的 ComboBox

在您的资源部分,您将使用以下内容:

<!-- Make sure this namespace is declared so that it's in scope below -->
.. xmlns:sys="clr-namespace:System;assembly=mscorlib" ..

<ObjectDataProvider MethodName="GetType" 
    ObjectType="{x:Type sys:Type}" x:Key="colorsTypeOdp">
    <ObjectDataProvider.MethodParameters>
        <sys:String>System.Windows.Media.Colors, PresentationCore,
            Version=3.0.0.0, Culture=neutral, 
            PublicKeyToken=31bf3856ad364e35</sys:String>
    </ObjectDataProvider.MethodParameters>
</ObjectDataProvider>
<ObjectDataProvider ObjectInstance="{StaticResource colorsTypeOdp}"  
    MethodName="GetProperties" x:Key="colorPropertiesOdp">
</ObjectDataProvider>

CodeNaked points out ,它可以简化为一个标签:

<ObjectDataProvider 
    ObjectInstance="{x:Type Colors}" 
    MethodName="GetProperties" 
    x:Key="colorPropertiesOdp" />

<ComboBox Name="comboBox1" 
    ItemsSource="{Binding Source={StaticResource colorPropertiesOdp}}"
    DisplayMemberPath="Name"
    SelectedValuePath="Name" />

casperOne's code :

<ComboBox Name="cboColors"
          ItemsSource="{Binding Source={StaticResource colorPropertiesOdp}}"
          SelectedValuePath="Name">
     <ComboBox.ItemTemplate>
        <DataTemplate>
           <StackPanel Orientation="Horizontal" Height="18" Margin="0,0,0,2">
              <Border BorderThickness="1" CornerRadius="2" 
                  BorderBrush="Black" Width="50" VerticalAlignment="Stretch"
                  Background="{Binding Name}"/>
              <TextBlock Text="{Binding Name}" Margin="8,0,0,0"/>
           </StackPanel>
         </DataTemplate>
     </ComboBox.ItemTemplate>
</ComboBox>

以下是我在过去的ASP.net应用程序中所做的操作:

// populate colors drop down (will work with other kinds of list controls)
Type colors = typeof(System.Drawing.Color);
PropertyInfo[] colorInfo = colors.GetProperties(BindingFlags.Public |
    BindingFlags.Static);
foreach ( PropertyInfo info in colorInfo)
{
    ddlColor.Items.Add(info.Name);                
}

// Get the selected color
System.Drawing.Color selectedColor = 
    System.Drawing.Color.FromName(ddlColor.SelectedValue);

using System.Reflection;

void ListAllColors()
{
    Type colorsType = typeof(System.Windows.Media.Colors);
    PropertyInfo[] colorsTypePropertyInfos = colorsType.GetProperties(BindingFlags.Public | BindingFlags.Static);

    foreach (PropertyInfo colorsTypePropertyInfo in colorsTypePropertyInfos)
        Debug.WriteLine(colorsTypePropertyInfo.Name);
}

_comboBox.Items.Add(colorsTypePropertyInfo.Name);
