C# 在2个子字符串之间拆分字符串而不删除分隔符

c# wpf string

C# 在2个子字符串之间拆分字符串而不删除分隔符,c#,wpf,string,delimiter,C#,Wpf,String,Delimiter,我有一根像 "<Canvas Background="#FF00FFFF" Name="Page_1" Width="1200" Height="900" ><TextBlock Name="PageTitle" /></Canvas><Canvas Background="#FF00FFFF" Name="Page_2" Width="1200" Height="900"><TextBlock Name="PageTitle" />&

我有一根像

"<Canvas Background="#FF00FFFF" Name="Page_1" Width="1200" Height="900" ><TextBlock Name="PageTitle" /></Canvas><Canvas Background="#FF00FFFF" Name="Page_2" Width="1200" Height="900"><TextBlock Name="PageTitle" /></Canvas>"

“”

我想把这个字符串分成一个数组

[< Canvas Background="#FF00FFFF" Name="Page_1" Width="1200" Height="900" >< TextBlock Name="PageTitle" />< /Canvas>],

[< Canvas Background="#FF00FFFF" Name="Page_2" Width="1200" Height="900">< TextBlock Name="PageTitle" />< /Canvas>]

[]，
