public static PropertyInfo GetPropertyInfo<TOwner, TProperty>(
	Expression<Func<TOwner, TProperty>> getPropertyExpression
)

Parameters

getPropertyExpression

Type: System.Linq.ExpressionsExpressionFuncTOwner, TProperty
An expression calling the getter of a property, for example (Type t) => t.FullName.

Type Parameters

TOwner

The type of the owner of the property.

TProperty

The type of the property.

Return Value

Both TOwner and TProperty are automatically deduced from the expression passed for getPropertyExpression and therefore do not need to be specified explicitly.

This method is helpful whenever code needs to retrieve the PropertyInfo associated with the property of a given type.

It is superior to GetDeclaredProperty(String), because it avoids duplicating the name of the property in a string. Such duplicated names are often forgotten during refactoring and the resulting bugs can only be found during testing. The specified expression is a language element that is checked for consistency at compile time and is automatically changed during refactoring.
