The write-up will explain the process of converting a string to double in C#. Change an Input String to “Double” in C# In C#, “Double” is basically a floating point number with 15 digits. We use double to store values of decimal numbers. There are three methods in C# for convertin...
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。
Another way to convert a double to an integer in C# is by casting the double to an integer, here is an example code that demonstrates this method: using System; class Program{ staticvoidMain(string[]args){ doublenumber=10.5; intintegerNumber=(int)number; ...
}// This property returns the number of elements in the object.publicintCount {get{returndata.Count; } }// This method calculates the average of the object's elements.protecteddoubleAverage(AverageType avgType){doubleSumProd;if( data.Count ==0)return0.0;switch( avgType ) {caseAverageType.G...
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...

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(...
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: ...
Next, we use theConvert.ToDouble()function to convert this string representation to a double-precision floating-point number, storing the result in thedoubleValuevariable. Finally, we print the converted double value to the console usingConsole.WriteLine(). ...
(Convert String to Double) In the C Programming Language, thestrtod functionconverts a string to a double. The strtod function skips all white-space characters at the beginning of the string, converts the subsequent characters as part of the number, and then stops when it encounters the first...
