我是C＃的新手 - 我在这里有一个'寻宝'游戏 - 它在一个盒子里隐藏't'，然后用户输入坐标 - 如果他们得到't'它说他们赢了如果没有，则显示“m”。
我正在尝试设置与用户输入的名称相关联的保存游戏。它将保存游戏写入txt文件并存储它 - 这很有效。但是当我尝试加载游戏时，我不断收到错误“索引超出了数组的范围”。

如果文件中的值如下所示
m m m m m m m m m m m m m m X m m X m m m m m m m m m m m X m m
然后你可以尝试这种方法
int i = 0;
// Read the file and work it line by line.
string[] lines = File.ReadAllLines(gameFile);
foreach(string line in lines)
{
string[] columns = line.Split(' ');
for(int j = 0; j < columns.Length; j++)
{
loadedBoarder[i, j] = columns[j];
}
i++;
}
@captainjamie：感谢您更正我的代码。

您的保存有9行，但您的电路板尺寸定义为10
答案 2 :(得分：0)
GetUpperBound返回，正如MSDN所说
获取指定维度的最后一个元素的索引 阵列。
所以，无论你在哪里使用这种方法，你都会得到9。要修复代码，您需要在保存和初始化Board数组时更改循环，并使用＆lt; =作为循环退出条件
