c# - 在 silverlight 中从字符串转换为数据？

Question

基本上我正在尝试这样做:

Path path = new Path( ); 

string sData = "M 250,40 L200,20 L200,60 Z";

var converter = TypeDescriptor.GetConverter( typeof( Geometry ) );
path.Data = ( Geometry )converter.ConvertFrom( sData );

但它不会编译，silverlight 似乎没有 TypeDescriptor 类...

Answer 1

试试这个:-

  Path path = XamlReader.Load("<Path Data=\"M 250,40 L200,20 L200,60\" />") as Path;

编辑

应该是:

  public static GeneratePath(string data)
  {
      string pathEnvelope = "<Path xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\" Data=\"{0}\"/>")
      return XamlReader.Load(String.Format(pathEnvelope, data)) as Path;
  }

用法:-

  string data = "M 250,40 L200,20 L200,60";

  Path path = GeneratePath(data);
