Suppose I have the following expressions:
Expression<Action<T, StringBuilder>> expr1 = (t, sb) => sb.Append(t.Name);
Expression<Action<T, StringBuilder>> expr2 = (t, sb) => sb.Append(", ");
Expression<Action<T, StringBuilder>> expr3 = (t, sb) => sb.Append(t.Description);
I'd like to be able to compile these into a method/delegate equivalent to the following:
void Method(T t, StringBuilder sb)
{
sb.Append(t.Name);
sb.Append(", ");
sb.Append(t.Description);
}
What is the best way to approach this? I'd like it to perform well, ideally with performance equivalent to the above method.
