C# 数组的使用

string[] sg1 = { "a", "b", "c", "d" };
foreach(string item in sg1){
onsole.Write(item+" ");
}
Console.WriteLine();

int[,] i1 = new int[3, 3] { { 11, 12, 13 }, { 21, 22, 23 }, {31, 32, 33} };

//多维数组foreach直接打印
foreach(int i in i1){
Console.Write(i+" ");
}
Console.WriteLine();

//多维数组按for循环排列打印,i由行元素的大小来限制；
for (int i = i1.GetLowerBound(0); i <= i1.GetUpperBound(0); i++)
{
Console.Write("第"+i+"维:{");

// j由列元素的大小来限制；
for (int j = i1.GetLowerBound(1); j <= i1.GetUpperBound(1); j++)
{
Console.Write("(元素{0}{1}:{2}) ", i, j, i1.GetValue(i, j));
}
Console.WriteLine("}");
}
Console.WriteLine();
