c# - 如何使用文化将变量中的波斯数字转换为英文数字？

Question

我想更改保存在变量中的波斯数字，如下所示：

string Value="۱۰۳۶۷۵۱";

到

string Value="1036751";

请问我怎样才能使用像文化信息这样的简单方法来做到这一点？

我的示例代码是：

List<string> NERKHCOlist = new List<string>();
NERKHCOlist = ScrappingFunction(NERKHCO, NERKHCOlist);
int NERKHCO_Price = int.Parse(NERKHCOlist[0]);//NERKHCOlist[0]=۱۰۳۶۷۵۱

<= 所以它不能将它解析为 int
这在我的函数中，它在列表项中重新调整一个带有波斯数字的列表

protected List<string> ScrappingFunction(string SiteAddress, List<string> NodesList)
{    
    string Price = "null";
    List<string> Targets = new List<string>();
    foreach (var path in NodesList)
    {
        HtmlNode node = document.DocumentNode.SelectSingleNode(path.ToString());//recognizing Target Node
        Price = node.InnerHtml;//put text of target node in variable(PERSIAN DIGITS)
        Targets.Add(Price);
    }
    return Targets;
}

只需使用以下代码：

private string changePersianNumbersToEnglish(string input)
{
  string[] persian = new string[10] { "۰", "۱", "۲", "۳", "۴", "۵", "۶", "۷", "۸", "۹" };

   for (int j=0; j<persian.Length; j++)
      input = input.Replace(persian[j], j.ToString());

   return input;
 }

我建议两种方法来处理这个问题（我为每个方法创建一个扩展方法）：

1.foreach 和替换

public static class MyExtensions
{
     public static string PersianToEnglish(this string persianStr)
     {
            Dictionary<char, char> LettersDictionary = new Dictionary<char, char>
            {
                ['۰'] = '0',['۱'] = '1',['۲'] = '2',['۳'] = '3',['۴'] = '4',['۵'] = '5',['۶'] = '6',['۷'] = '7',['۸'] = '8',['۹'] = '9'
            };
            foreach (var item in persianStr)
            {
                persianStr = persianStr.Replace(item, LettersDictionary[item]);
            }
            return persianStr;
     }
}

2.字典.聚合

public static class MyExtensions
{
      public static string PersianToEnglish(this string persianStr)
      {
            Dictionary<string, string> LettersDictionary = new Dictionary<string, string>
            {
                ["۰"] = "0",["۱"] = "1",["۲"] = "2",["۳"] = "3",["۴"] = "4",["۵"] = "5",["۶"] = "6",["۷"] = "7",["۸"] = "8",["۹"] = "9"
            };
            return LettersDictionary.Aggregate(persianStr, (current, item) =>
                         current.Replace(item.Key, item.Value));
      }
}

使用文化将数字从任何语言转换为任何语言

职能：

public static string ConvertDigitChar(this string str, CultureInfo source, CultureInfo destination)
{
    for (int i = 0; i <= 9; i++)
    {
        str = str.Replace(source.NumberFormat.NativeDigits[i], destination.NumberFormat.NativeDigits[i]);
    }
    return str;
}

public static string ConvertDigitChar(this int digit, CultureInfo destination)
{
    string res = digit.ToString();
    for (int i = 0; i <= 9; i++)
    {
        res = res.Replace(i.ToString(), destination.NumberFormat.NativeDigits[i]);
    }
    return res;
}

如何使用功能：

var fa = CultureInfo.GetCultureInfoByIetfLanguageTag("fa");
var en = CultureInfo.GetCultureInfoByIetfLanguageTag("en");
string str = "۰0۱1۲2۳3۴4۵5۶6۷7۸8۹9";
string r1 = str.ConvertDigitChar(en, fa);
string r2 = str.ConvertDigitChar(fa, en);
int i = 123456789;
string r3 = i.ConvertDigitChar(fa);

结果：

r1："۰۰۱۱۲۲۳۳۴۴۵۵۶۶۷۷۸۸۹۹"

r2："00112233445566778899"

r3："۰۱۲۳۴۵۶۷۸۹"

您需要首先解析它们，例如使用带有正确文化说明符的 Int32.Parse()。一旦你把它作为一个纯整数，它只是一个简单的调用 ToString() 的问题，再次使用正确的文化说明符。

另一种解决方案是逐个字符地遍历字符串，并将波斯数字的任何字符替换为相应的（西方）阿拉伯数字。如果需要，其他字符可以按原样保留。

如果字符串确实包含数字，则应使用整数解析方法。如果它不仅仅是一个数字，而是一个电话号码、序列号等，您可能需要使用替换算法。

您可以像这样手动转换它们

    char[][] numbers = new char[][]
    {
        "0123456789".ToCharArray(),"persian numbers 0-9 here".ToCharArray()
    };
    public void Convert(string problem)
    {
        for (int x = 0; x <= 9; x++)
        {
            problem.Replace(numbers[0][x], numbers[1][x]);
        }
    }

我不知道波斯数字，所以您必须将它们添加到 char 数组中。

Saeed 的解决方案是好的，但是对于双变量，您还必须将“٫”字符替换为“。” ，所以你可以使用：

private string ToEnglishNumber(string strNum)
{
string[] pn = { "۰", "۱", "۲", "۳", "۴", "۵", "۶", "۷", "۸", "۹", "٫" };
string[] en = { "0", "1", "2", "3", "4", "5", "6", "7", "8", "9","." };
string chash = strNum;
for (int i = 0; i < 11; i++)
    chash = chash.Replace(pn[i], en[i]);
return chash;
}
