There is a .NET 3.5 way with lambdas/Expression
that doesn’t use strings…
using System;
using System.Linq.Expressions;
using System.Reflection;
class Foo
{
public string Bar { get; set; }
}
static class Program
{
static void Main()
{
PropertyInfo prop = PropertyHelper<Foo>.GetProperty(x => x.Bar);
}
}
public static class PropertyHelper<T>
{
public static PropertyInfo GetProperty<TValue>(
Expression<Func<T, TValue>> selector)
{
Expression body = selector;
if (body is LambdaExpression)
{
body = ((LambdaExpression)body).Body;
}
switch (body.NodeType)
{
case ExpressionType.MemberAccess:
return (PropertyInfo)((MemberExpression)body).Member;
default:
throw new InvalidOperationException();
}
}
}
