組合框綁定源

Question

林已如下因素WPF窗口：

 <Window x:Class="WpfApplication1.MainWindow" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     xmlns:ports="clr-namespace:System.IO.Ports;assembly=System" 
     Title="MainWindow" 
     SizeToContent="WidthAndHeight"> 
    <Window.Resources> 
     <ObjectDataProvider x:Key="portNames" 
          MethodName="GetPortNames" 
          ObjectType="{x:Type ports:SerialPort}" /> 
    </Window.Resources> 
    <ComboBox Name="cbox" ItemsSource="{Binding Source={StaticResource portNames}}" SelectionChanged="ComboBox_SelectionChanged" /> 

</Window> 

我米使用ObjectDataProvider的填充COM端口組合框。 但我不知道如何填充其他組合框。使用 C＃功能：

private void LoadBaudRates() 
     { 
      cboxBaudRate.DataContext = new int[] { 9600, 14400, 19200, 38400, 57600, 115200, 128000 }; 
      cboxBaudRate.SelectedIndex = 0; 
     } 
     private void LoadParity() 
     { 
      cboxParity.DataContext = Enum.GetValues(typeof(Parity)); 
     } 
     private void LoadFlowControl() 
     { 
      cboxFlowControl.DataContext = Enum.GetValues(typeof(Handshake)); 
     } 
     private void LoadCOMPorts() 
     { 
      var comPorts = SerialPort.GetPortNames(); 
      //cboxCOMPorts.DataContext = comPorts; 
      this.cboxCOMPorts.DataContext = comPorts; 
     }

如果你想在XAML來填充其他ComboBoxes然後Enum你還可以創建ObjectDataProvider，因爲你做了與COM端口：

<ObjectDataProvider x:Key="HandshakeValues" MethodName="GetValues" ObjectType="{x:Type sys:Enum}"> 
    <ObjectDataProvider.MethodParameters> 
     <x:Type TypeName="ports:Handshake" /> 
    </ObjectDataProvider.MethodParameters> 
</ObjectDataProvider> 

<ComboBox ItemsSource="{Binding Source={StaticResource HandshakeValues}}"/> 

和int數組，你可以做像這樣：

<ComboBox> 
    <ComboBox.ItemsSource> 
     <x:Array Type="{x:Type sys:Int32}"> 
     <sys:Int32>9600</sys:Int32> 
     <sys:Int32>14400</sys:Int32> 
     <sys:Int32>19200</sys:Int32> 
     <sys:Int32>38400</sys:Int32> 
     <sys:Int32>57600</sys:Int32> 
     <sys:Int32>115200</sys:Int32> 
     <sys:Int32>128000</sys:Int32> 
     </x:Array> 
    </ComboBox.ItemsSource> 
</ComboBox> 

其中sys是xmlns:sys="clr-namespace:System;assembly=mscorlib"
