Number这个用Convert。ToDouble（）是无法转换的，会报错，因为Number是字符串，不是有效的数字，是无法转换的。你要是想把字符串转换成数字是不行的，只能转换成字节码这类东西。这个可以自己写，因为可以找找函数。
You pass the string representation of the numeric value as an argument, and the function returns the equivalent double-precision floating-point number.Here’s a basic example:double doubleValue = Double.Parse(stringValue); In this example, Double.Parse() is used to convert the string string...
uint[] numbers = { UInt32.MinValue, 121, 12345, UInt32.MaxValue }; double result; foreach (uint number in numbers) { result = Convert.ToDouble(number); Console.WriteLine("Converted the UInt32 value {0} to {1}.", number, result); } // The example displays the following output: ...

How can I convert a value to Double in JavaScript??? Convert it to a number. All numbers in JavaScript are doubles. If the value you convert from is a string representation, you can use either Number(value) or parseFloat(valu e). The first requires the value to be a syntactically cor...
Double 雙精確度浮點數,其與 value 相等。 屬性 CLSCompliantAttribute 範例 下列範例會將值Double陣列UInt32中的每個項目轉換成值。 C# 複製 執行 uint[] numbers = { UInt32.MinValue, 121, 12345, UInt32.MaxValue }; double result; foreach (uint number in numbers) { result = Convert.ToDouble(...
enter something like this. When I execute my code I am getting error that not possible to convertchar**todoublein assignment. The character I have implemented for conversion isnumvalidationto validate the user input just for first value, if input is number then accept else return de...
Double 一个等于 value 的双精度浮点数。 属性 CLSCompliantAttribute 示例 以下示例将值数组 UInt32 中的每个元素转换为 Double 值。 C# 复制 运行 uint[] numbers = { UInt32.MinValue, 121, 12345, UInt32.MaxValue }; double result; foreach (uint number in numbers) { result = Convert.ToDoubl...
