獲取 C# 中陣列指定維度中的元素總數
要獲取陣列指定維度中的元素總數,程式碼如下 -
示例
using System; public class Demo { public static void Main() { string[] products = new string[] { "Andy", "Mark", "Gary", "Andre"}; Console.WriteLine("One or more name begins with 'A'? = {0}", Array.Exists(products, ele => ele.StartsWith("A"))); Console.WriteLine("Is the array having fixed size? = " + products.IsFixedSize); Console.WriteLine("Is the array read only? = " + products.IsReadOnly); Console.WriteLine("Is the array synchronized? = " + products.IsSynchronized); Console.WriteLine("Index of the 1st element = "+products.GetLowerBound(0)); Console.WriteLine("Index of the last element = "+products.GetUpperBound(0)); Console.WriteLine("GetLongLength(0) = "+products.GetLongLength(0)); } }
輸出
這將產生以下輸出 -
One or more name begins with 'A'? = True Is the array having fixed size? = True Is the array read only? = False Is the array synchronized? = False Index of the 1st element = 0 Index of the last element = 3 GetLongLength(0) = 4
我們現在來看另一個示例 -
示例
using System; public class Demo { public static void Main() { string[,, ] stdNames = new string[,, ] { { { "John", "Gary" }, { "Jacob", "Harry" } }, { { "Kevin", "Ryan" }, { "David", "Mark" } },}; Console.WriteLine("Is the array having fixed size? = " + stdNames.IsFixedSize); Console.WriteLine("Is the array read only? = " + stdNames.IsReadOnly); Console.WriteLine("Is the array synchronized? = " + stdNames.IsSynchronized); Console.WriteLine("Index of the 1st element = "+stdNames.GetLowerBound(0)); Console.WriteLine("Index of the last element = "+stdNames.GetUpperBound(0)); Console.WriteLine("GetLongLength(0) = "+stdNames.GetLongLength(0)); Console.WriteLine("GetLongLength(0) = "+stdNames.GetLongLength(1)); } }
輸出
這將產生以下輸出 -
Is the array having fixed size? = True Is the array read only? = False Is the array synchronized? = False Index of the 1st element = 0 Index of the last element = 1 GetLongLength(0) = 2 GetLongLength(0) = 2
