我有一个日期,例如 12/05/2012 现在我想将该格式更改为简单的字符串。

例如。

string newdate = new string();
newdate = "12/05/2012";
DateTime Bdate = DateTime.ParseExact(Newdate, "dd/MM/yyyy", System.Globalization.CultureInfo.InvariantCulture);

现在我的 BDate 是DateTime ie。BDate= 2012/05/12

现在我想做类似的事情

如果我的日期是 2012 年 5 月 12 日,那么我想要一个类似于“12 May 2012”的字符串

我怎样才能做到这一点?

请帮我...

提前致谢....

您需要查看每个日期部分并使用函数来获取书面等价物。我在下面包含了一个将整数转换为书面文本的类,并将其扩展为支持DateTime转换:

public static class WrittenNumerics
{
    static readonly string[] ones = new string[] { "", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine" };
    static readonly string[] teens = new string[] { "Ten", "Eleven", "Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen", "Seventeen", "Eighteen", "Nineteen" };
    static readonly string[] tens = new string[] { "Twenty", "Thirty", "Forty", "Fifty", "Sixty", "Seventy", "Eighty", "Ninety" };
    static readonly string[] thousandsGroups = { "", " Thousand", " Million", " Billion" };

    private static string FriendlyInteger(int n, string leftDigits, int thousands)
    {
        if (n == 0)
            return leftDigits;

        string friendlyInt = leftDigits;
        if (friendlyInt.Length > 0)
            friendlyInt += " ";

        if (n < 10)
            friendlyInt += ones[n];
        else if (n < 20)
            friendlyInt += teens[n - 10];
        else if (n < 100)
            friendlyInt += FriendlyInteger(n % 10, tens[n / 10 - 2], 0);
        else if (n < 1000)
            friendlyInt += FriendlyInteger(n % 100, (ones[n / 100] + " Hundred"), 0);
        else
            friendlyInt += FriendlyInteger(n % 1000, FriendlyInteger(n / 1000, "", thousands + 1), 0);

        return friendlyInt + thousandsGroups[thousands];
    }

    public static string DateToWritten(DateTime date)
    {
        return string.Format("{0} {1} {2}", IntegerToWritten(date.Day), date.ToString("MMMM"), IntegerToWritten(date.Year));
    }

    public static string IntegerToWritten(int n)
    {
        if (n == 0)
            return "Zero";
        else if (n < 0)
            return "Negative " + IntegerToWritten(-n);

        return FriendlyInteger(n, "", 0);
    }
}

免责声明:@Wedge提供的基本功能

使用此类,只需调用 DateToWritten 方法:

var output = WrittenNumerics.DateToWritten(DateTime.Today);

上面的输出是:Twelve May Two Thousand Twelve

这不是您想要的,但我可以建议使用内置功能的最接近的方法是ToLongDateString,它为您提供月份的名称,并且显然对文化敏感。

string str = bdate.ToLongDateString();
// Assuming en-US culture, this would give: "Saturday, May 12, 2012"

假设 12/05/2012 是一个字符串,那么您必须将其标记为以斜杠“/”分隔的元素。例如:

“12/05/2012”-> [“12”、“05”、“2012”]

接下来,您为自己定义一个规则,将这些元素解析为您所期望的。比如说,“12”是“十二”,“05”是“五”或“五月”等。

string MyDate = "12/05/2012";
DateTime expected = Convert.ToDateTime(MyDate);
string MyNewDate = expected.ToString("dd MMM yyyy");
