原文:https://www . geesforgeks . org/c-sharp-convert-tostringstring-iformat provider-method/

此方法用于返回指定的字符串实例，并且不执行实际转换。 语法:

public static string ToString (String, IFormatProvider);

参数:

  • 值:返回的字符串。
  • 提供程序:它是一个提供区域性特定格式信息的对象。此参数被忽略。

返回值:此方法返回值不变返回。 下面的程序说明了转换的使用。方法: 例 1:

c sharp . c sharp . c sharp . c sharp

// 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 initializing 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);
    }
}

Output: 

Converted string value from a specified string:  amar  akbar  anthony

例 2:

c sharp . c sharp . c sharp . c sharp

// 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);
    }
}
