命名空間'System.Windows'中不存在類型或命名空間名稱'Deployment'

Question

我目前正試圖通過將文件鏈接到wpf librarys來將我的silverlight項目更改爲wpf，以便以後我可以同時使用這兩個應用程序。我鏈接到我的WPF項目從我的Silverlight項目這個文件是給我這個錯誤：

Error 27 The type or namespace name 'Deployment' does not exist in the namespace 'System.Windows' (are you missing an assembly reference?) C:\Users\sahluwai\Desktop\cusControls2\leitch\HarrisSilverlightToolkit\Toolkit\Source\Controls\Input\IpAddressControl\CcsIPAddressControl.cs 854 36 Input

我已經確定該文件已經「使用System.Windows」排在首位。

這是什麼功能的樣子，其中有錯誤（請認準評論看一個例子出錯位置）：

private bool ValidateIpOctet(TextBox IpOctet, int OctetIndex) 
    { 
     bool redraw = false; 

     if (OctetIndex < 0 || OctetIndex >= this.m_IpAddress.IpOctets.Length) 
      return redraw; 

     int i = OctetIndex; 

     this.m_IpAddress.IpOctets[i] = String.IsNullOrEmpty(IpOctet.Text) ? "0" : IpOctet.Text; 

     uint iOctet = uint.Parse(this.m_IpAddress.IpOctets[i]); 
     if (i == 0) 
     { 
      if (Rule == NetworkInterfaceRule.IP || Rule == NetworkInterfaceRule.GATEWAY) 
      { 
       if (iOctet > 223) 
       { 
        redraw = true; 
        this.m_IpAddress.IpOctets[i] = "223";

         }); 
       } 
       else if (iOctet < 1) 
       { 
        redraw = true; 
        this.m_IpAddress.IpOctets[i] = "1"; 
        System.Windows.Deployment.Current.Dispatcher.BeginInvoke(

         }); 
       } 
      }

       { 
        redraw = true;

不要System.Windows.Deployment使用調度程序 - 這是特定的Silverlight。如果您的意圖是調用屬於GUI的分派器上的某些內容，請改用System.Windows.Application.Current.Dispatcher。
