Re: how to declare array of struct

Would be along these lines:

C# Syntax (Toggle Plain Text)
public struct MyStruct
 
      {
 
        public string text;
 
        public string text2;
 
        public int number;
 
      }
public struct MyStruct

      {

        public string text;

        public string text2;

        public int number;

      }

Some basic information

Re: how to declare array of struct

Hey Shadowwrider,

<code>
ArrayList ar = new ArrayList();
object[] myarray = new object[2];
</code>

ArrayList comes from the System.Collection name space. I find it very useful, and will show you how to use the array or arraylist. Above I declare both for your consideration. Notice that for the standard array, you need to declare it as an array of objects.

In this example we have a very simple struct:
<code>
public struct MyStruct
{
public int t1;
public string s1;
}
</code>

Here is a Simple example using some Console writing:
<code>
ArrayList ar = new ArrayList();
object[] myarray = new object[2];
// First get an instance of the struct
MyStruct thisjoe;
thisjoe.t1 = 1;
thisjoe.s1 = "Hello";
myarray[0] = thisjoe; // Add to the Array
ar.Add(thisjoe); // OR add to the ArrayList

// Do another one
thisjoe.t1 = 2;
thisjoe.s1 = "World";
ar.Add(thisjoe);
myarray[1] = thisjoe;

// How to get a value ? Lets put one into (x)
int x = ((MyStruct)ar[0]).t1;
Console.WriteLine("X={0}", x);

// Lets go through the ArrayList
foreach (MyStruct myjoe in ar)
{
Console.WriteLine("{0}:{1}", myjoe.s1, myjoe.t1);
}

// Lets go through the standard Array
foreach (MyStruct myjoe in myarray)
{
Console.WriteLine("{0}:{1}", myjoe.s1, myjoe.t1);
}
</code>

Hope this Helps,
Jerry

This isn't java. Next time use code tags.
