public static RepositoryExtensionsExpressionDependencies GetExpressionDependencies(
	this Repository repository,
	Expression expression
)

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type Repository. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
Remarks
The GetExpressionDependencies(Repository, Expression) method traverses the full expression tree and returns each reference to an attribute, which is from the repository. The method does not return references to attributes from other repositories. For example:
Copy
salesOrdersRepository.GetDependantAttributes(so => ((SalesOrder)so).Customer.Name);
would return "SalesOrder.Customer", but would not return "Customer.Name".
