In C# visual studio not taking decimal points in double after read and converted into double using

命令...例如，如果键入12.25，它将值保存为1225.我可以帮忙吗? 这是我正在使用的代码.

command... For example if 12.25 is typed it saves the value as 1225. Can I get any help? This is the Code i'm using.

double number;
Console.WriteLine("Enter a number with a two decimal places!");
number = Convert.ToDouble(Console.ReadLine());
Console.WriteLine(number):
Console.ReadLine();

推荐答案

您当前的代码应能按预期工作，否则，可能是文化问题导致您的双字符串采用不同格式的结果(即12,25而不是12.25).

Your current code should be working as expected and if it isn't, it's likely the result of cultural issues that expect your double string to be in a different format (i.e. 12,25 instead of 12.25).

解析时应用当前区域性

在 处理各种文化(即句号或逗号)

如果您希望处理句点或逗号，则可以用相同的方式执行替换:

If you wanted to expect to handle either periods or commas, you could potentially perform a replacement the in the same manner :

// Get the number separator for this culture and replace any others with it
var separator = CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSeparator;
// Replace any periods or commas with the current culture separator and parse
var input = Double.Parse(Regex.Replace(Console.ReadLine(),"[.,]",separator));

您可以在此处查看有效的示例.
