数组相加的问题

[weiqj8686]

数组arr1[0,0]={{"a","b"},{"e","f","g"}};arr2={"a","e"}

我想通过arr1和arr2得到
结果为：arr3[0,0]={{"a"+"e","b"+"e"},{"a"+"e","a"+"f","a"+"g"}}

怎么做？

我的做法是双循环。但我知道效率低。

string[][] myArray = new string[2][];
myArray[0] = new string[2] {"a","b" };
myArray[1] = new string[3] { "e", "f","g" };
string[] a = new string[2] { "a", "e" };
for (int i = 0; i < myArray.Length; i++)
{

if (i == 0)
{
for (int j = 0; j < myArray[0].Length; j++)
{
myArray[0][j] += a[1];
}
}
else
{
for (int j = 0; j < myArray[1].Length; j++)
{
myArray[1][j] += a[0];
}
}

}
foreach (string[] c in myArray)
{
foreach (string b in c)
{
Response.Write(b + " ");
}
Response.Write("<br>");
}


这样的?

如果楼主是想明白例子中数组如何相加的话：
arr3[i] = arr1[i] + arr2[arr2.length-1-i]
= {arr1[0] + arr2[arr2.length-1], arr1[0] + arr2[arr2.length-2], ... , arr1[i] + arr2[0]}

用你给的例子的话就是这个样子
arr3[0] = arr1[0] + arr2[1]
= {arr1[0,0] + arr2[1],arr1[0,1] + arr2[1]}
= {"a"+"e","b"+"e"}
arr3[1] = arr1[1] + arr2[0]
= {arr1[1,0] + arr2[0],arr1[1,1] + arr2[0],arr1[1,2] + arr2[0]}
= {"a"+"e","a"+"f","a"+"g"}

如果你想问的是其他问题，请澄清一下。
