foreach loops in JScript / C#Script...

Question

Hi All,I have the following bit of C# sample code "lifted" from the net...sdsforeach&nbsp;(Item myItem&nbsp;in&nbsp;findResults.Items)"findResults"&nbsp;is of type&nbsp;Microsoft.Exchange.WebServices.Data.FindItemsResults&nbsp;while&nbsp;"findResults.Items"&nbsp;is of type System.Collections.ObjectModel.CollectionThe problem is - I've tried both JScript and C#Script, I *cannot* specify the type of object "myItem" is in the foreach loop. And I've tried NOT specifying the type:"foreach (item myitem in findResults.Items)" &nbsp;&lt;&lt;&lt; syntax error"foreach (myitem in findResults.Items)" &lt;&lt;&lt;&lt; Object expected error at run time.Can someone help as to how to write this foreach loop in C#Script / Jscript?Thanks

Hi, Steve, JScript has no concept of a foreach loop such as that prescribed in C#, I would use the approach of an old school for loop

for( var i = 0; i < findResults.Items.Count; i++ ) {

myItem = findResults.Items[ i ];

// Proces myItem...

}

The closest approximation to foreach is the for..in loop but this iterates over the properties of an object so can produce unexpected results and needs to be used carefully and with the hasOwnProperty() method as well as other safe guards

Apologies, the forum has decided to render the collection indexing as an italic, hopefully this will work...

for( var j = 0; j < findResults.Items.Count; j++ ) {

myItem = findResults.Items[ j ];

// Proces myItem...

}

Actually, the square bracket notation I showed probably will not work, this does work though and may be of use

var sa = dotNET.System_Collections.ArrayList.zctor();

sa.Add( "a" );

sa.Add( "b" );

sa.Add( "c" );

var s;

for( var i = 0; i < sa.Count; i++ ) {

s = sa.Item( i );

Log.Message( s );

}

The following also works

var l = sa.GetEnumerator();

while( l.MoveNext() ) {

s = l.Current;

Log.Message( s );

}

I could not get for...in to work in any form, I kept gettting the following error

Microsoft JScript runtime error.

Hope this helps

Hi Steve,You Wrote: "foreach (item myitem in findResults.Items)" &lt;&lt;&lt; syntax errorThat is because you must declare a var type.You wrote: "foreach (myitem in findResults.Items)" &lt;&lt;&lt;&lt; Object expected error at run time.myItem was auto-declared as a var type and findResults is undefined/null.It seems that you might&nbsp;want to checkout the CLR bridge to add a reference to the dlls&nbsp;that contain the two classes you mentionned. Documentation is hereSincerely&nbsp;

they do have a"for in" loop which is similar to "for each"http://msdn.microsoft.com/en-us/library/y3wd7kkh(v=vs.100).aspxandhttp://msdn.microsoft.com/en-us/library/4z08sst3%28v=vs.100%29.aspx

Thanks all - indeed, I also failed on the for..in front...

Good old fashioned for (x = 0; x < y; x++) was the way that ultimately got there...

Arguably not the "cleanest" solution, but does what it says on the tin :)
