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.Clear method is used to remove all the strings from the StringCollection.
Syntax:
public void Clear ();
Note:
- Count is set to zero, and references to other objects from elements of the collection are also released.
- This method is an O(n) operation, where n is Count.
Example:
// C# code to insert a string into // the StringCollection at the // specified index using System;
using System.Collections;
using System.Collections.Specialized;
class GFG {
// Driver code
public static void Main()
{
// creating a StringCollection named myCol
StringCollection myCol = new StringCollection();
// creating a string array named myArr
String[] myArr = new String[] { "Hello" , "Geeks" ,
"for" , "GeeksforGeeks" };
// Copying the elements of a string
// array to the end of the StringCollection.
myCol.AddRange(myArr);
Console.WriteLine( "Initially elements in StringCollection are: " );
// Displaying elements in StringCollection
// named myCol
foreach (Object obj in myCol)
Console.WriteLine(obj);
// Removing all the elements from StringCollection
myCol.Clear();
Console.WriteLine( "After Removing: " );
// Displaying elements in StringCollection
// named myCol
foreach (Object obj in myCol)
Console.WriteLine(obj);
}

Output:
Initially elements in StringCollection are: Hello Geeks for GeeksforGeeks After Removing:
