convert 'String' to 'System.Collections.ICollection'

[SIMIN]

Hi,

 

A component I use needs a collection to be added to it.

I get a list from user in a multi line text box.

So how can I add it?

The list is multi line but is string and object needs collection.

So when I use this:

 

ThirdPartyObject.List.AddRange(ListTextBoxX.Text)

 

Warning 1 Runtime errors might occur when converting 'String' to 'System.Collections.ICollection'.

You could just pass ListTextBoxX.Lines rather than .Text to the method.

In your case PD's idea to use the .Lines property is probably ideal.

 

If for some reason you have similar data; but not in a TextBox control, you could try code like the following:

 

// some delimited string
String text = "Some Text, Line Two, Line Three";
// split text by delim save array result
// define this as an array (the code tags are making my square brakets show up wrong)
String sItems = text.Split(',');

// add each item to the list
foreach (String item in sItems)
{
   If(item != String.Empty)
       ThirdPartyObject.List.Add(item);
}
