输入字符串在Convert.ToDouble（“ Infinity”）上的格式不正确

Question

Why would the following fail with a System.FormatException on 64-bit Windows 10, but runs fine on 32-bit Windows 7? Both machines have .NET Framework 4.6.1 installed.

Convert.ToDouble("Infinity");

I have searched and cannot find an answer to this.

Answer 1

The string used for Infinity is culture specific and may have even had different values between Win 7 & 10 (can't confirm that at the moment).

Try using the constant instead of hard coding a string:

Convert.ToDouble(NumberFormatInfo.PositiveInfinitySymbol);
