C# |布尔型。比较(布尔)方法

原文:https://www . geeksforgeeks . org/c-sharp-boolean-compare tool-method/

布尔。比较(布尔)方法用于将当前实例与指定的布尔对象进行比较，并返回它们相对值的指示。

语法:

public int CompareTo (bool value);

这里，值是一个布尔对象，用于与当前实例进行比较。

返回值:这个方法返回一个 32 位有符号整数，表示这个实例和值的相对顺序。

  • is less than zero: If this instance is false , the value is true .
  • Zero: If this instance and value are equal (either both are true or both are false ).
  • is greater than zero: If this instance is true, is false .

例:

// C# program to demonstrate
// Boolean.CompareTo(Boolean)
// Method
using System;

class GFG {

    // Main Method
    public static void Main()
    {

        // Declaring val1 and val2
        bool val1, val2;

        // intializing the val1,
        // and val2
        val1 = true;
        val2 = false;

        // using CompareTo method
        int i = val2.CompareTo(val1);

        // checking the condition
        if (i > 0)
            Console.Write("val2 is greater than val1");

        else if (i < 0)
            Console.Write("val2 is less than val1");

        else
            Console.Write("val1 is equal to val1");
    }
}

输出:

val2 is less than val1
