以下示例程序旨在說明Convert.ToString(String，IFormatProvider)方法的用法：

範例1：

// C# program to demonstrate the 
// Convert.ToString() Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // creating object of CultureInfo 
            CultureInfo cultures =  
              new CultureInfo("en-US"); 
  
            // declaring and intializing String array 
            string[] values = {"amar", "akbar", 
                                    "anthony"}; 
  
            // calling get() Method 
            Console.Write("Converted string value"
                  + " from a specified string:"); 
  
            for (int j = 0; j < values.Length; j++)  
            { 
                get(values[j], cultures); 
            } 
        } 
  
        catch (FormatException e)  
        { 
            Console.WriteLine("\n"); 
            Console.Write("Exception Thrown:"); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
  
        catch (OverflowException e)  
        { 
            Console.WriteLine("\n"); 
            Console.Write("Exception Thrown:"); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
  
    // Defining get() method 
    public static void get(string s, 
               CultureInfo cultures) 
    { 
  
        // converting string to specified string 
        string val = Convert.ToString(s, cultures); 
  
        // display the converted string value 
        Console.Write(" {0} ", val); 
    } 
}
輸出： 
Converted string value from a specified string: amar  akbar  anthony

範例2：

// C# program to demonstrate the 
// Convert.ToString() Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // creating object of CultureInfo 
        CultureInfo cultures =  
          new CultureInfo("en-US"); 
  
        // declaring and initializing a String array 
        string value = "The Accidental Prime Minister"; 
  
        // calling get() Method 
        Console.Write("Converted String:"); 
  
        // converting string to specified string 
        string val = Convert.ToString(value, cultures); 
  
        // display the converted string value 
        Console.Write("{0}", val); 
    } 
}
