“{ Binding Path = . }”在 WPF 绑定中是什么意思？

在 WPF 绑定中，{Binding Path=.}意味着什么？

我看到一些人使用它，但找不到任何解释。

绑定语法中是否有其他特殊符号({Binding /}除外) ？

This is shorthand for binding to the current source. For more info see here.

From the documentation specifically:

Optionally, a period (.) path can be used to bind to the current source. For example, Text="{Binding}" is equivalent to Text="{Binding Path=.}".

I found this WPF Binding CheatSheet a few months back and find it very useful, especially for anyone learning WPF. There are some spelling mistakes within it, but it is still quite good.

Here is a small excerpt (which is supposed to have tabular formatting):

Basic Binding
{Binding} Bind to current DataContext.
{Binding Name} Bind to the “Name” property of the current DataContext.
{Binding Name.Length} Bind to the Length property of the object in the Name property of the current DataContext.
{Binding ElementName=SomeTextBox, Path=Text} Bind to the “Text” property of the element XAML element with name=”SomeTextBox” or x:Name=”SomeTextBox”.
