Help with c# variables

[Lambert Symth]

How can i use a variable from within a different function in which it was
not set.
Like the example.

using System;

namespace test
{
class class1
{
static void Main()
{
string name = "bob";
start();
}

static void start()
{
Console.WriteLine(name);
}
}
}

Currently the variable is a local variable - it's only available within
the method. You need to declare it as a static variable:

using System;

namespace test
{
class class1
{
static string name;

static void Main()
{
name = "bob";
start();
}

static void start()
{
Console.WriteLine(name);
}
}
}

You could pass it as a parameter like this

using System;

namespace test
{
class class1
{
static void Main()
{
string name = "bob";
start(name);
}

static void start(string name)
{
Console.WriteLine(name);
}
}
}

That still won't compile (start is static) and even if it did, it would
print out an empty string rather than bob, as the local variable would
shadow the static/instance one.

In addition, your variable casing is somewhat odd (why change the OP's
variable name?) and variables shouldn't be public...

Almost. If you get rid of the double declaration, this would likely work.
Replace this:
string Name = "bob";
with this
Name = "bob";

(I'm guessing that this was your intent.)

Also, the variable could be declared 'private' instead. That would be
better data hiding.

To the OP: the best solution is to pass the variable as a parameter.
