C# | Remove the first occurrence from the StringCollection
StringCollection class is a new addition to the .NET Framework class library that represents a collection of strings. StringCollection class is defined in the System.Collections.Specialized namespace.
StringCollection.Remove(String) method is used to remove the first occurrence of a specific string from the StringCollection.
public void Remove (string value);
Here, value is the string which is to be removed from the StringCollection. The value can be null.
- Duplicate strings are allowed in StringCollection.
- Only the first occurrence is removed. To remove all occurrences of the specified string, use RemoveAt(IndexOf(value)) repeatedly while IndexOf does not return -1.
- If the StringCollection does not contain the specified object, the StringCollection remains unchanged. No exception is thrown.
- This method performs a linear search; therefore, this method is an O(n) operation, where n is Count.
Elements in StringCollection are : A A A B C C D D E Elements in StringCollection are : A A B C C D D E Elements in StringCollection are : A A B C D D E Elements in StringCollection are : A B C D D E Elements in StringCollection are : A B C D D E
