在google中搜索后，使用下面的代码仍然无法编译:
decimal h = Convert.ToDecimal("2.09550901805872E-05");
decimal h2 = Decimal.Parse(
"2.09550901805872E-05",
System.Globalization.NumberStyles.AllowExponent);
最佳答案
您还必须添加 NumberStyles.AllowDecimalPoint:
Decimal.Parse("2.09550901805872E-05", NumberStyles.AllowExponent | NumberStyles.AllowDecimalPoint);
MSDN对此很清楚:
Indicates that the numeric string can be in exponential notation. The AllowExponent flag allows the parsed string to contain an exponent that begins with the "E" or "e" character and that is followed by an optional positive or negative sign and an integer. In other words, it successfully parses strings in the form nnnExx, nnnE+xx, and nnnE-xx. It does not allow a decimal separator or sign in the significand or mantissa; to allow these elements in the string to be parsed, use the AllowDecimalPoint and AllowLeadingSign flags, or use a composite style that includes these individual flags.
