Hi All,

I am new to .net and i have a situation where need to write the foreach loop but i am not aware of it exactly but i wrote for loop. Can anyone help me converting the below code to foreach?

Below is my code:

C#

List<Int32> multiObject = ((List<Int32>)favoriteDocumentsField.Value);
     for (int index = 0; index < multiObject.Count; index++) {
          Int32 docID = multiObject[index];
          Console.WriteLine("Artifact: {0} Field: {1} Value: {2}", employee.ArtifactID, favoriteDocumentsField.Name + " Object " + index, docID);
     }

Any help would be appreciated.

What I have tried:

I tried searching in google. I got the direct FOREACH loop examples and used but didn't get the conversion from the for to foreach.

Untested

C#

List<Int32> multiObject = ((List<Int32>)favoriteDocumentsField.Value);
     foreach (int docID in multiObject) {
          Console.WriteLine("Artifact: {0} Field: {1} Value: {2}", employee.ArtifactID, favoriteDocumentsField.Name, docID);
     }

I've dropped writing the index value from your WriteLine as it no longer exists. If you really want that index value you're better leaving it as a for loop. You could have index as its own variable and increment it inside the foreach, but there is not point in doing that when you can keep it as a for loop instead.

List<int32> multiObject = ((List<int32>)favoriteDocumentsField.Value);
foreach (int docID in multiObject) {
emailAddress += docID.Artifact.Fields[0].Value.ToString() + ";";
}
In the above code, i am getting an error near Artifact inside loop stating int does not contain a definition for Artifact.

That's because docID is an int, so you can't do

docID.Artifact

You need to know what exactly has the Atrifact property if you want to access it.
