转换为浮点数的最佳/最快方法 [英] Best/quickest way to convert to float

问题描述

所以我试图输入和输出浮点数.

So I am trying to have input and output in float number.

Console.WriteLine("Enter float number: ");
float number = Console.ReadLine();
Console.WriteLine("{0}", number);

我看到ReadLine将具有字符串格式的问题，这将导致错误CS0029:无法将类型'string'隐式转换为'float'(CS0029)".现在，如何将字符串转换为float?我可以使用float.Parase:

I see the problem that ReadLine will have format in string which will cause "Error CS0029: Cannot implicitly convert type 'string' to 'float' (CS0029)". Now, how do I convert string to float? I could use float.Parase:

string unformattedNumber;
float number;

Console.WriteLine("Enter float number: ");
unformattedNumber = Console.ReadLine();

number = float.Parse(unformattedNumber);

Console.WriteLine("{0}", number);

但是有没有更好的方法可以在与ReadLine语句相同的行中进行转换?

But is there any better way to convert in same line as ReadLine statement is at?

推荐答案

TryParse是最好的方法.
