System.Globalization.NumberFormatInfo numberFormatInfo =
(System.Globalization.NumberFormatInfo)System.Globalization.NumberFormatInfo.CurrentInfo.Clone();

推荐答案
var result1 = Double.NaN.ToString();
var numberFormatInfo = System.Globalization.NumberFormatInfo.CurrentInfo.Clone() as System.Globalization.NumberFormatInfo;
var result2 = numberFormatInfo.NaNSymbol;
result1和result2应该相同。
result1 and result2 should be the same.
