C#中的Int64.ToString()方法用于将该实例的数值转换为其等效的字符串表示形式。
语法如下-
public override string ToString (); public string ToString (string format);
上面的参数格式是数字格式字符串。
现在让我们看一个例子-
using System; public class Demo { public static void Main(){ long val1 = 0; long val2 = Int64.MaxValue; Console.WriteLine("Value1 = "+val1.ToString()); Console.WriteLine("Value2 = "+val2.ToString()); Console.WriteLine("Are they equal? = "+val1.Equals(val2)); Console.WriteLine("Value1 (HashCode) = "+val1.GetHashCode()); Console.WriteLine("Value2 (HashCode) = "+val2.GetHashCode()); TypeCode type1 = val1.GetTypeCode(); TypeCode type2 = val2.GetTypeCode(); Console.WriteLine("TypeCode for val1 = "+val1.GetTypeCode()); Console.WriteLine("TypeCode for val2 = = "+val1.GetTypeCode()); } }
输出结果
这将产生以下输出-
Value1 = 0 Value2 = 9223372036854775807 Are they equal? = False Value1 (HashCode) = 0 Value2 (HashCode) = -2147483648 TypeCode for val1 = Int64 TypeCode for val2 = = Int64
现在让我们来看另一个示例-
using System; public class Demo { public static void Main(){ long val1 = 87987687; long val2 = 35436367; Console.WriteLine("Value1 = "+val1.ToString("D8")); Console.WriteLine("Value2 = "+val2.ToString("X")); Console.WriteLine("Are they equal? = "+val1.Equals(val2)); Console.WriteLine("Value1 (HashCode) = "+val1.GetHashCode()); Console.WriteLine("Value2 (HashCode) = "+val2.GetHashCode()); TypeCode type1 = val1.GetTypeCode(); TypeCode type2 = val2.GetTypeCode(); Console.WriteLine("TypeCode for val1 = "+val1.GetTypeCode()); Console.WriteLine("TypeCode for val2 = = "+val1.GetTypeCode()); } }
输出结果
这将产生以下输出-
Value1 = 87987687 Value2 = 21CB74F Are they equal? = False Value1 (HashCode) = 87987687 Value2 (HashCode) = 35436367 TypeCode for val1 = Int64 TypeCode for val2 = = Int64
