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.Count property is used to get the number of strings contained in the StringCollection.
Syntax:
public int Count { get; }
Return Value: It returns the number of strings contained in the StringCollection.
Note: Retrieving the value of this property is an O(1) operation.
Below programs illustrate the use of StringCollection.Count Property:
Example 1:
// C# code to get the number of strings // contained in the StringCollection 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[] { "First" , "Second" , "Third" ,
"Fourth" , "Fifth" };
// Copying the elements of a string
// array to the end of the StringCollection.
myCol.AddRange(myArr);
// To get number of Strings contained
// in the StringCollection
Console.WriteLine( "Number of strings in myCol are : " + myCol.Count);
}
} |
Output:
Number of strings in myCol are : 5
Example 2:
// C# code to get the number of strings // contained in the StringCollection 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[] {};
// Copying the elements of a string
// array to the end of the StringCollection.
myCol.AddRange(myArr);
// To get number of Strings contained
// in the StringCollection
Console.WriteLine( "Number of strings in myCol are : " + myCol.Count);
}
} |
Output:
Number of strings in myCol are : 0
