Provides a means of passing context state among serializers. This class cannot be inherited.
Assembly: System.Design (in System.Design.dll)
|ExpressionContext(CodeExpression, Type, Object)|
Initializes a new instance of theclass with the given expression and owner.
|ExpressionContext(CodeExpression, Type, Object, Object)|
Initializes a new instance of theclass with a current value.
Determines whether the specified object is equal to the current object.(Inherited from Object.)
Serves as the default hash function. (Inherited from Object.)
Returns a string that represents the current object.(Inherited from Object.)
Anis placed on the context stack and contains the most relevant expression during serialization. The following C# code demonstrates an assignment.
button1.Text = "Hello";
During serialization, several serializers are responsible for creating this single statement. One of those serializers is responsible for creating "Hello". There are times when that serializer may need to know the context in which it is creating its expression. In the previous example, this context is not needed. The following C# code shows a situation in which knowledge of the context is necessary.
button1.Text = rm.GetString("button1_Text");
In this case, the serializer responsible for creating the resource expression needs to be informed of the names of the target objects. Theclass can be used for this. As each serializer creates an expression and invokes a serializer to handle a smaller part of the statement as a whole, the serializer pushes an expression context on the context stack. Each expression context has a parent property that locates the next expression context on the stack. This provides a convenient traversal capability.
