How to avoid short circuit evaluation in C# while doing the same functionality

Do we have any operator in C# by which I can avoid short circuit evaluation and traverse to all the conditions.

say

if(txtName.Text.xyz() || txtLastName.Text.xyz())
{

}

public static bool xyz(this TextBox txt)
{
//do some work.
return false;
}

It should evaluate all conditions irrespective of output obtained. And after evaluating last condition continues according to result obtained. ?
