Using foreach

[tony]

Hello

I use foreach when I have a container of some kind for example an array or
ArrayList.

But in this case is it really possible to use foreach. In case it is how
would I write it.

for( int i = 0; i < dSMspCompositio n.Tables[0].Rows.Count; i++ )
compositionList .Add(dSMspCompo sition.Tables[0].Rows[i]["COMP_NAME"]);
//Tony

you can use foreach over the datarow collection:

foreach (DataRow row in dSMspCompositio n.Tables[0].Rows)
{
compositionList .Add(row["COMP_NAME"]);
}

Tony,

You can use foreach on any object that supports IEnumerable interface or has
instance GetEnumerator method declared.

BTW I wonder why ArraySegment<T> doesn't have a GetEnumerator<T >.

Is there an easy way of foreach'ing an ArraySegment<T> or a T[] array?

Not sure. That's a bit odd.

You can certainly foreach over T[]. Here's an example:

using System;

class Foo<T>
{
T[] x;

public Foo(T[] data)
{
x = data;
foreach (T t in x)
{
Console.WriteLi ne(t);
}
}
}

class Test
{
static void Main()
{
new Foo<string>(new string[]{"hello", "there"});
}
}
