Complex.Zero 字段

定义

返回新的 Complex 实例,其实数和虚数都等于零。Returns a new Complex instance with a real number equal to zero and an imaginary number equal to zero.

public: static initonly System::Numerics::Complex Zero;
public static readonly System.Numerics.Complex Zero;
 staticval mutable Zero : System.Numerics.Complex
Public Shared ReadOnly Zero As Complex 

字段值

示例

下面的示例通过使用 Zero 属性将 Complex 值实例化。The following example instantiates a Complex value by using the Zero property. 然后,它会将此值与另一个值进行比较,方法是调用 Complex 构造函数,该构造函数的实部等于零,虚部等于零。It then compares this value to another value that is instantiated by calling the Complex constructor with a real part equal to zero and an imaginary part equal to zero. 如示例中的输出所示,这两个值相等。As the output from the example shows, the two values are equal.

using System;
using System.Numerics;

public class Example
{
   public static void Main()
   {
      Complex value = Complex.Zero;
      Console.WriteLine(value.ToString());
      
      // Instantiate a complex number with real part 0 and imaginary part 1.
      Complex value1 = new Complex(0, 0);
      Console.WriteLine(value.Equals(value1));
   }
}
// The example displays the following output:
//       (0, 0)
//       True
Imports System.Numerics

Module Example
   Public Sub Main()
      Dim value As Complex = Complex.Zero
      Console.WriteLine(value.ToString())
      
      ' Instantiate a complex number with real part 1 and imaginary part 0.
      Dim value1 As New Complex(0, 0)
      Console.WriteLine(value.Equals(value1))
   End Sub
End Module
' The example displays the following output:
'       (0, 0)
'       True

注解

Zero 属性最常用于将 Complex 值与零进行比较。The Zero property is most frequently used to compare a Complex value to zero.
