for 循环遍历数组
- 数组遍历
- 遍历取值
int[] intArray = new int[]{11,22,33,44,55,66,77,88,99};
for(int i = 0; i <= intArray.Length - 1; i++) //intArray.Length:取得当前数组长度.
{
Console.WriteLine(intArray[i]);
}
Console.ReadKey();
- 遍历赋值
string[] str = new string[5];
for (int i = 0; i <= str.Length - 1; i++)
{
str[i] = "元素" + i;
}
for (int j = 0; j <= str.Length; j++)
{
Console.WriteLine(str[j]);
}
Console.ReadKey();
- 练习:定义一个字符串数组存放12生肖,循环遍历该数组,将元素组合成一个字符串,且元素与元素之间用' | '分割。12生肖数组元素如下:"子鼠","丑牛","寅虎","卯兔","辰龙","巳蛇","午马","未羊","申猴","酉鸡","戌狗","亥猪".
string[] animals = new string[] { "子鼠", "丑牛", "寅虎", "卯兔", "辰龙", "巳蛇", "午马", "未羊", "申猴", "酉鸡", "戌狗", "亥猪" };
string animalStr = "";
for (int i = 0; i < animals.Length; i++)
{
animalStr += animals[i];
if(i < animals.Length - 1)
{
animalStr += "|";
}
}
Console.WriteLine(animalStr);
Console.ReadKey();
foreach 遍历数组
- 语法
foreach( 数组数据类型 临时变量 in 数组名)
{
Console.WriteLine( 临时变量 );
}
int[] intArray = new int[]{1,2,3,4,5,6,7,8,9};
foreach(int i in intArray)
{
Console.WriteLine(i);
}
Console.ReadKey();
数组元素的初始值
- 数组初始化完成后,各种类型的数组的默认值:
- int[]:元素的值默认都是0;
- float:元素的值默认都是0;
- double:元素的值默认都是0.0;
- string:元素的值默认都是 null;
- bool:元素的值默认都是 false;
