Is string reference type / value type?..

Answer / guest

Simple types (such as float, int, char), enum types and
struct types are all value types.
Note that many types (such as string) appear in some ways
to be value types, but in fact are reference types. These
are known as immutable types

Is string reference type / value type?..

Answer / n

Hi Guys

If any of you got so far.. Here is the deal:

The differnce between value types and reference types are
whether the information is stored in the stack or on the
heap. Design guidelines for designing structures (value
type, stored in the stack) is that it's instance value
should be less than 16 bytes.

In the .NET Framework, ALL value types are 16 bytes or
shorter.

A string can be a lot more than 16 bytes...

It does however act like a value type in order to make the
programming easier for us... This can be the reason for all
this confusion...

Now stop arguing and start converting coffee into code....

Is string reference type / value type?..

Answer / akn

Everything not derived from System.ValueType is a reference
type.
So System.String is reference type.

Is string reference type / value type?..

Answer / ak

How do you explain this then?

public void MyTest()
{
Program myClass = new Program();
myClass.value = 1;
Console.Out.WriteLine(myClass.value.ToString
()); //1
Program newClass = myClass;

newClass.value = 2;
Console.Out.WriteLine(myClass.value.ToString
()); //2

myClass.strvalue = new String("1".ToCharArray
());

Console.Out.WriteLine(myClass.strvalue); //1
newClass.strvalue = myClass.strvalue;

newClass.strvalue = "2";
Console.Out.WriteLine(myClass.strvalue); //2
}

Is string reference type / value type?..

Answer / n.

There is no magic.... You can test all the types:

using System;
using System.Collections.Generic;
using System.Text;

namespace List_Value_Types
{
class Program
{
static void Main(string[] args)
{
SByte a = 0;
Byte b = 0;
Int16 c = 0;
Int32 d = 0;
Int64 e = 0;
string s = "";
Exception ex = new Exception();

object[] types = { a, b, c, d, e, s, ex};

foreach (object o in types)
{
string type = "";
if (o.GetType().IsValueType)
type = "Value type";
else
type = "Reference type";

Console.WriteLine("{0}: {1}", o.GetType(),
type);
}
Console.ReadKey();
}
}
}
