UInt64。将 C# 中的()方法与示例进行比较
原文:https://www . geeksforgeeks . org/uint 64-compare to-method-in-c-sharp-with-examples/
UInt64。比较方法用于将当前实例与指定的对象或另一个 UInt64 实例进行比较。它返回一个整数，该整数显示当前实例的值是小于、等于还是大于指定对象或其他 UInt64 实例的值。此方法的重载列表中有 2 种方法，如下所示:

UInt64。比较(UInt64)方法
此方法用于将当前实例与指定的 64 位无符号长整数进行比较，并返回一个整数，该整数显示当前实例的值是小于、等于还是大于指定的 64 位无符号长整数的值。
语法:
cs public int CompareTo (ulong value);这里，需要一个无符号长值来进行比较。
返回值:返回一个 32 位有符号数，表示当前实例和值参数的相对值，如下所示:
- 小于零:如果当前实例<值
- 如果当前实例=值，则为零:
- 大于零:如果当前实例>值
以下程序说明了 UInt64 的使用。比较(UInt64) 方法:
例 1:
```cs // C# program to demonstrate the // UInt64.CompareTo(UInt64) Method using System;
class GFG {
// Main Method public static void Main() {
// Declaring and initializing value1 ulong value1 = 312312131231;
// Declaring and initializing value2 ulong value2 = 523564123;
// using CompareTo() method int status = value1.CompareTo(value2);
// checking the status if (status > 0) Console.WriteLine("{0} is greater than {1}", value1, value2); else if (status < 0) Console.WriteLine("{0} is less than {1}", value1, value2); else Console.WriteLine("{0} is equal to {1}", value1, value2); } } ```
Output:
```cs 312312131231 is greater than 523564123
```
例 2:
```cs // C# program to demonstrate the // UInt64.CompareTo(UInt64) Method using System;
class GFG {
// Main Method public static void Main() { // calling get() method get(34432425, 708343); get(3780, 8920); get(8543453910, 85345340920); get(7006789, 7006789); }
// defining get() method public static void get(ulong value1, ulong value2) {
// using CompareTo() method int status = value1.CompareTo(value2);
// checking the status if (status > 0) Console.WriteLine("{0} is greater than {1}", value1, value2); else if (status < 0) Console.WriteLine("{0} is less than {1}", value1, value2); else Console.WriteLine("{0} is equal to {1}", value1, value2); } } ```
Output:
```cs 34432425 is greater than 708343 3780 is less than 8920 8543453910 is less than 85345340920 7006789 is equal to 7006789
```
UInt64。比较对象方法
此方法用于将当前实例与指定的对象进行比较，并返回一个整数，该整数指示当前实例的值是小于、等于还是大于对象的值。
语法:
cs public int CompareTo (object value);这里，它将对象与这个实例进行比较，或者为 null。
返回值:返回一个 32 位有符号数，表示当前实例和值参数的相对值，如下所示:
- 小于零:如果当前实例<值
- 如果当前实例=值，则为零:
- 大于零:如果当前实例>值
异常:如果值不是 UInt64，则抛出参数异常。
以下程序说明了 UInt64 的使用。比较(对象)方法
例 1:
```cs // C# program to demonstrate the // UInt64.CompareTo(Object) Method using System;
class GFG {
// Main Method public static void Main() { try {
// Declaring and initializing value1 ulong value1 = 2324313420;
// Declaring and initializing value2 object value2 = (ulong)687.876;
// using CompareTo() method int status = value1.CompareTo(value2);
// checking the status if (status > 0) Console.WriteLine("{0} is greater than {1}", value1, value2);
else if (status < 0) Console.WriteLine("{0} is less than {1}", value1, value2); else Console.WriteLine("{0} is equal to {1}", value1, value2); }
catch (ArgumentException e) { Console.WriteLine("value2 must be null"+ " or an instance of UInt32"); Console.Write("Exception Thrown: "); Console.Write("{0}", e.GetType(), e.Message); } } } ```
Output:
```cs 2324313420 is greater than 687
```
示例 2: 适用于参数异常
```cs // C# program to demonstrate the // UInt64.CompareTo(Object) Method using System; using System.Globalization;
class GFG {
// Main Method public static void Main() { try {
// Declaring and initializing value1 ulong value1 = 104646549854;
// Declaring and initializing value2 object value2 = 1 / 6;
// using CompareTo() method int status = value1.CompareTo(value2);
// checking the status if (status > 0) Console.WriteLine("{0} is greater than {1}", value1, value2);
else if (status < 0) Console.WriteLine("{0} is less than {1}", value1, value2); else Console.WriteLine("{0} is equal to {1}", value1, value2); }
catch (ArgumentException e) { Console.WriteLine("value2 must be null"+ " or an instance of UInt64"); Console.Write("Exception Thrown: "); Console.Write("{0}", e.GetType(), e.Message); } } } ```
Output:
```cs value2 must be null or an instance of UInt64 Exception Thrown: System.ArgumentException
```
