Question

如何将 TextBox.Text 绑定(bind)到 myDictionary["testElement"]？

Answer 1

您是否尝试过删除 testElement 周围的引号？如果 key 是一个应该有效的字符串。

From MSDN :

Indexers of a property can be specified within square brackets following the property name where the indexer is applied. For instance, the clause Path=ShoppingCart[0] sets the binding to the index that corresponds to how your property's internal indexing handles the literal string "0". Multiple indexers are also supported.

[...]

Inside indexers you can have multiple indexer parameters separated by commas (,). The type of each parameter can be specified with parentheses. For example, you can have Path="[(sys:Int32)42,(sys:Int32)24]", where sys is mapped to the System namespace.
