This method is used to releases all resources used by the current instance of the CharEnumerator class. The Dispose() method leaves the CharEnumerator in an unusable state. So, this method should be called when a user finished their working with the CharEnumerator.
Syntax:
public void Dispose ();
Return Value: This method returns nothing.
Below are the programs to illustrate the use of CharEnumerator.Dispose() Method:
Example 1:
// C# program to illustrate the // use of CharEnumerator.Dispose() // Method using System;
class GFG {
// Driver code
public static void Main()
{
// Initialize a string object
string str = "GeeksforGeeks is Awesome!" ;
// Instantiate a CharEnumerator object
CharEnumerator chEnum = str.GetEnumerator();
// Print the string using CharEnumerator
while (chEnum.MoveNext())
Console.Write(chEnum.Current);
// CharEnumerator object is disposed
chEnum.Dispose();
// Try printing current character
// using CharEnumerator
try
{
Console.Write(chEnum.Current);
}
catch (Exception e)
{
Console.Write( "\nShows " + e.GetType() + " as" +
" the CharEnumerator object is disposed." );
}
}
} |
Output:
GeeksforGeeks is Awesome! Shows System.NullReferenceException as the CharEnumerator object is disposed.
Example 2:
// C# program to illustrate the // use of CharEnumerator.Dispose() // Method using System;
class GFG {
// Driver code
public static void Main()
{
// Initialize a string object
string str = "GeeksforGeeks is Awesome" ;
// Instantiate a CharEnumerator object
CharEnumerator chEnum = str.GetEnumerator();
while (chEnum.MoveNext())
{
// Print current character
Console.Write(chEnum.Current);
// Dispose the CharEnumerator object
// when space is encountered
if (chEnum.Current == ' ' )
{
Console.WriteLine( ".\nDispose CharEnumerator object and " +
"try to print current character." );
chEnum.Dispose();
break ;
}
}
// Try printing current character
// using CharEnumerator
try
{
Console.Write(chEnum.Current);
}
catch (Exception e)
{
Console.Write( "Shows " + e.GetType() + " as the" +
" CharEnumerator object is disposed." );
}
}
} |
Output:
GeeksforGeeks . Dispose CharEnumerator object and try to print current character. Shows System.NullReferenceException as the CharEnumerator object is disposed.
