How can I list colors in WPF with XAML?
提问by
How can I get list of all colors I can pick in Visual Studio Designer (which is System.Windows.Media.Colors, but that isn't a collection) and put them into my own ComboBoxusing WPF and XAML markup?
如何获取我可以在 Visual Studio 设计器中选择的所有颜色的列表（它是System.Windows.Media.Colors，但不是一个集合），并ComboBox使用 WPF 和 XAML 标记将它们放入我自己的列表中？

Here is the pure XAML solution.
这是纯 XAML 解决方案。
In your resources section, you would use this:
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>
Or, as CodeNaked points out, it can be reduced to one tag:
或者，正如CodeNaked 指出的那样，它可以简化为一个标签：
<ObjectDataProvider
ObjectInstance="{x:Type Colors}"
MethodName="GetProperties"
x:Key="colorPropertiesOdp" />
And then the combobox would look like this:
然后组合框看起来像这样：
<ComboBox Name="comboBox1"
ItemsSource="{Binding Source={StaticResource colorPropertiesOdp}}"
DisplayMemberPath="Name"
SelectedValuePath="Name" />

Here is what I have done in a past ASP.net app:
这是我在过去的 ASP.net 应用程序中所做的：
// 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);

Here is a great ItemTemplate to use for a combobox using casperOne's code:
这是一个很棒的 ItemTemplate 用于使用casperOne 代码的组合框：
<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>

Here's how to do it in code using reflection. The following will dump all predefined WPF color names to Output:
下面是如何使用反射在代码中做到这一点。以下将转储所有预定义的 WPF 颜色名称到输出：
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);
}
And to put them in a combobox, you could simply change the last line to:
要将它们放在组合框中，您只需将最后一行更改为：
_comboBox.Items.Add(colorsTypePropertyInfo.Name);
