GetPropertyInfo

Returns the PropertyInfo of the property specified by the source expression

{
    public int Id { get; set; }
    public string Name { get; set; }

    public static PropertyInfo GetPropertyInfo(
        Expression<Func<MyClass, object>> expression)
    {
        return expression.GetPropertyInfo();
    }
}

var propertyInfo = MyClass.GetPropertyInfo(c => c.Name);
/*
    propertyInfo will contain the PropertyInfo instance for the "Name" property
*/

GetPropertyName

Returns the property name of the property specified by the source expression

public class MyClass
{
    public int Id { get; set; }
    public string Name { get; set; }

    public static string GetPropertyName(
        Expression<Func<MyClass, object>> expression)
    {
        return expression.GetPropertyName();
    }
}

var propertyName = MyClass.GetPropertyInfo(c => c.Name);
/*
    propertyName will be "Name"
*/
