Return array from method

[Westerberg]

Is it possible to pass an array from a method?

An example below:


array GetArray()
{
SqlConnection conn = new SqlConnection("Server=127.0.0.1;User ID=me;Pwd=dude;database=mine;);
SqlDataReader rdr = null;
conn.Open();
SqlCommand cmd = new SqlCommand("select * from Table", conn);
rdr = cmd.ExecuteReader();
string[,] names = new string[cnt,6]; //creates a two dimensional array
rdr.Read(); //initial read
for (int i=1; i < cnt; i++)
{
for (int j=1; j < 6; j++)
{
names[i,j] = rdr[j].ToString();
}
rdr.Read();
}
conn.Close();
return names
}

Is it possible to pass an array from a method?

yourType[] function()
{
// create array
yourType[] arr = ...;

// return array
return arr;
}

Well there is the other way, but it`s used in a little diferrent situation that you describes. You can use it to send an array to function to change it and have it back

void SomeFunc(out type [] array)
{
//some actions with array
}

noooooo.. dont tell people that when they havent got the basics understood.. :)

out and ref parameter modifiers should be left well alone until the developer knows the difference between the stack and the heap

Its true, I am working on the basics but I did find the out and ref parameter modifiers while searching. I'm using the code that wildfrog showed me since it works and a problem hasn't come up with it.

Why not, we always need to learn smth new :rolleyes:
And as for me the basics are heap, stack reference and other things that are principal to programming language. What was nice in C all of this was easy to understand during first applications and in c# you may not see them but often use
