Declaration

public ExpressionHelper()

Methods

GetExpressionPath(Expression)

Gets a string representation of the member expressions in an expressions body possibly containing multiple levels. Example: Type A has a property TheB of type B which has a property TheC of any type. Calling this method with the body of the expression a => a.TheB.TheC returns {"TheB", "TheC"}.

Declaration

protected virtual IEnumerable<string> GetExpressionPath(Expression expression)

Parameters

Type	Name	Description
System.Linq.Expressions.Expression	expression	The expression body to get the path for.

Returns

Type	Description
System.Collections.Generic.IEnumerable<System.String>	The full property path.

GetExpressionPath<T>(Expression<Func<T, Object>>)

Gets a string representation of the member expressions in an expressions body possibly containing multiple levels. Example: Type A has a property TheB of type B which has a property TheC of any type. GetFullPropertyName<A>(a => a.TheB.TheC) returns {"TheB", "TheC"}.

Declaration

public virtual IEnumerable<string> GetExpressionPath<T>(Expression<Func<T, object>> expression)

Parameters

Type	Name	Description
System.Linq.Expressions.Expression<System.Func<T, System.Object>>	expression	The expression of the property to get the path for.

Returns

Type	Description
System.Collections.Generic.IEnumerable<System.String>	The full property path.

Type Parameters

Name	Description
T	The type to get a property name for.

GetFullPropertyName<T>(Expression<Func<T, Object>>)

Gets a string representation of the member expressions in an expressions body possibly containing multiple levels. Example: Type A has a property TheB of type B which has a property TheC of any type. GetFullPropertyName<A>(a => a.TheB.TheC) returns "TheBTheC".

Declaration

public virtual string GetFullPropertyName<T>(Expression<Func<T, object>> expression)

Parameters

Type	Name	Description
System.Linq.Expressions.Expression<System.Func<T, System.Object>>	expression	The expression of the property name to get.

Returns

Type	Description
System.String	The full property path.

Type Parameters

Name	Description
T	The type to get a property name for.

GetFullPropertyName<T>(Expression<Func<T, Object>>, String)

Gets a string representation of the member expressions in an expressions body possibly containing multiple levels. Example: Type A has a property TheB of type B which has a property TheC of any type. GetFullPropertyName<A>(a => a.TheB.TheC) returns "TheBTheC".

Declaration

public virtual string GetFullPropertyName<T>(Expression<Func<T, object>> expression, string separator)

Parameters

Type	Name	Description
System.Linq.Expressions.Expression<System.Func<T, System.Object>>	expression	The expression of the property name to get.
System.String	separator	Optional separator between levels, defaults to no separator.

Returns
