Creating method using C# in ASP.NET with Razor syntax

Problem resolved: I found a reusable solution. Thank you everyone for your help.

I'm frustrated and don't know what I'm doing. I'm attempting to build a webpage and one of the things I'm trying to do is cut down on code. In order to do so, I need to create a method, I know extensively about methods from Java, but not when trying to write C# in ASP.NET using razor syntax. The problem I'm facing is my @helper refuses to access the global hash table "dictionary". I've tried a lot of different things and have decided to turn to stackoverflow for help. Thanks in advance.

UPDATES:

Error Message is "CS0103: The name 'dictionary' does not exist in the current context"

I need a hashtable because I'm pulling from a database, checking to see if its null, if yes, replacing it with an empty string, then pushing it to a table. So if I could learn how to do it in this fashion, it would work best, I think?

<!doctype html>

@using System;
@using System.Collections.Generic;
@using System.Collections;
@using System.Linq;

@{
    var dictionary = new Dictionary<string, object>();

    dictionary.Add("fName", returnString100.FRSTNAME.Trim());

    @helper printOut(string toBePrinted) {
        object curValue;
        if(dictionary.TryGetValue(toBePrinted, out curValue)) { 
            return curValue; 
        }
    }
}

<table>
    <tr>
        <td>First Name:</td><td>@{ printOut("fName"); }</td>
    </tr>
</table>

While philosophically I agree with the others that you might want to encapsulate this in a class, here's how you can do this in Razor with a view:

<!doctype html>

@using System;
@using System.Collections.Generic;
@using System.Collections;
@using System.Linq;

@{
    var dictionary = new Dictionary<string, object>();

    dictionary.Add("fName", returnString100.FRSTNAME.Trim());

    Func<string, object> PrintOut = delegate(string toBePrinted)
    {
        object curValue;
        if (dictionary.TryGetValue(toBePrinted, out curValue))
            return curValue;
        return "";   
    };

}

<table>
    <tr>
        <td>First Name:</td><td>@PrintOut("fName").ToString()</td>
    </tr>
</table>
