Array.length

説明

The length property that returns or sets the number of elements in the Array.

Use Array.length to get or set the size of the array. The example uses the C# Length property.

// C# array Length example
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    void Start()
    {
        // use string array approach
        string[] names = new string[] {"Hello", "World", "Really"};

        foreach (string s in names)
        {
            print("user is: " + s);
        }

        print("length is: " + names.Length);

        // use ArrayList approach
        ArrayList arr = new ArrayList();
        arr.Add("Hello");
        arr.Add("World");

        // ArrayList uses Count instead of Length
        print(arr.Count);
    }
}
