使用带ParserContext参数的Xaml.Load方法

原文:使用带ParserContext参数的Xaml.Load方法

如果一段XAML中存在一个标记需要从外部命名空间中解析， 就需要用到ParserContext类，  具体用法如下：

Normal
0

false
false
false

EN-US
ZH-CN
X-NONE

MicrosoftInternetExplorer4

/* Style Definitions */
table.MsoNormalTable
{mso-style-name:"Table Normal";
mso-tstyle-rowband-size:0;
mso-tstyle-colband-size:0;
mso-style-noshow:yes;
mso-style-priority:99;
mso-style-qformat:yes;
mso-style-parent:"";
mso-padding-alt:0in 5.4pt 0in 5.4pt;
mso-para-margin-top:0in;
mso-para-margin-right:0in;
mso-para-margin-bottom:10.0pt;
mso-para-margin-left:0in;
line-height:115%;
mso-pagination:widow-orphan;
font-size:11.0pt;
font-family:"Calibri","sans-serif";
mso-ascii-font-family:Calibri;
mso-ascii-theme-font:minor-latin;
mso-hansi-font-family:Calibri;
mso-hansi-theme-font:minor-latin;
mso-bidi-font-family:"Times New Roman";
mso-bidi-theme-font:minor-bidi;}

ParserContext

pc = new
ParserContext
();

     
pc.XmlnsDictionary.Add(""
, "http://schemas.microsoft.com/winfx/2006/xaml/presentation"
);

      pc.XamlTypeMapper = new
XamlTypeMapper
(new
string
[0]);

     
pc.XamlTypeMapper.AddMappingProcessingInstruction(

        "http://schemas.microsoft.com/winfx/2006/xaml/presentation"
,

        "ClassLibrary1"
,

        "ClassLibrary1"
);

      object
o = XamlReader
.Parse("<SharedResourceDictionary
Source=/"pack://application:,,,/KeyOfVictory;component/Dictionary1.xaml/"/>"
,
pc);

 

XmlnsDictionary属性中存储XML命名空间和命名空间前缀的对应关系， XamlTypeMapper类型中存储XML命名空间和CLR命名空间的对应关系， 并且还存储了定义CLR命名空间的程序集名称， 需要注意的是程序集名称就是程序集的partial name， 不需要有dll后缀。
