C# 是否可以int 数据类型保存文化特定数字，如东方阿拉伯语 数字?例如.123" 将是

Can C# int data type hold culture specific numbers like Eastern Arabic numbers? E.g. "123" will be

١٢٣

我正在使用 SoapUI 发送请求和接收响应.Web 服务是用 c# 编写的.

I’m working with SoapUI to send requests and receive responses. The web service is written in c#.

但是，当我在 Soap UI 中输入这些东方阿拉伯数字时，它说

However when I enter these Eastern Arabic numbers in Soap UI, it says

无法解析该值".

不清楚是 Soap UI 问题还是 c# 问题.

It’s not clear if it’s Soap UI issue or c# issue.

有人可以帮忙吗?

感谢您的回答！

推荐答案

您可以尝试使用 char.GetNumericValue 将文化特定数字(例如波斯语)转换为常见的0..9:

You can try using char.GetNumericValue to convert culture specific digits (e.g. Persian) into common 0..9:

private static bool TryParseAnyCulture(string value, out int result) {
  result = default(int);

  if (null == value)
    return false;

  StringBuilder sb = new StringBuilder(value.Length);

  foreach (char c in value) {
    double d = char.GetNumericValue(c);

    // d < 0      : character is not a digit, like '-'
    // d % 1 != 0 : character represents some fraction, like 1/2
    if (d < 0 || d % 1 != 0)
      sb.Append(c);
    else
      sb.Append((int)d);
  }

  return int.TryParse(sb.ToString(), out result);
}

演示:

string value = "١٢٣"; // Eastern Arabic Numerals (0..9 are Western)

Console.Write(TryParseAnyCulture(value, out var result) ? $"{result}" : "???");

结果:

123
