Question

我浏览了一些其他帖子，但似乎没有任何帮助。所以我想要的是一个代码，用一个美元金额读出当前的余额，前面有一个短语。而不是打印美元符号打印{0:C}。我错误地使用{0:C}吗？

namespace ConsoleApplication7
{
    class Program
    {
        static void Main(string[] args)
        {
            double TotalAmount;
            TotalAmount = 300.7 + 75.60;
            string YourBalance = "Your account currently contains this much money: {0:C} " + TotalAmount;
            Console.WriteLine(YourBalance);
            Console.ReadLine();
        }
    }
}

Answer 1

string YourBalance = 
    string.Format("Your account currently contains this much money: {0:C} ",TotalAmount);

或使用C＃6.0 +

的字符串插值

string YourBalance = $"Your account currently contains this much money: {TotalAmount:C} ";

Answer 2

我是否错误地使用{0：C}？

是的，你是。您只是将字符串与TotalAmount连接起来。因此，即使您使用货币格式说明符（{0:C}），货币金额也不会替换说明符。

您需要使用String.Format()，如下所示：

string YourBalance = String.Format("Your account currently contains this much money: {0:C}", TotalAmount);

Answer 3

你非常接近！您需要使用string.Format()：

string YourBalance = string.Format(
    "Your account currently contains this much money: {0:C} ", TotalAmount);

{0:C}语法并不代表Format方法的上下文之外的任何内容。

Answer 4

您可以使用此...

using System.Globalization;

namespace ConsoleApplication
{
   class Program
   {
       static void Main(string[] args)
       {
            double TotalAmount;
            TotalAmount = 300.7 + 75.60;
            string YourBalance = "Your account currently contains this much money: " +
                           string.Format(new CultureInfo("en-US"), "{0:C}",TotalAmount);
            Console.WriteLine(YourBalance);
            Console.ReadLine();
        }
    }
}
