C# 将二维字符串数组转换为二维整数数组（多维数组）

我想替换

string[，]

2D数组

public static readonly string[,] first =
{
    {"2", " ", " ", " ", "1"},
    {"2", " ", "4", "3", " "},
    {" ", "2", " ", "1", " "},
    {" ", "1", " ", "3", " "},
    {"1", " ", " ", " ", " "}
};

进入

int[，]

数组

int X=-1;
public static readonly int[,] second =  
{
    {2, X, X, X, 1},
    {2, X, 4, 3, X},
    {X, 2, X, 1, X},
    {X, 1, X, 3, X},
    {1, X, X, X, X}
};

是否可以将

字符串[，]

数组转换为

int[，]

数组？如果是，如何将

字符串[，]

转换为

int[，]

？谢谢。

使用您正在使用的循环，并用空值替换空字符串，如果要使用此数组，请先检查值是否为空。

string[，]=
string[,] first =
{
    {"2", " ", " ", " ", "1"},
    {"2", " ", "4", "3", " "},
    {" ", "2", " ", "1", " "},
    {" ", "1", " ", "3", " "},
    {"1", " ", " ", " ", " "}
};


int[,] second = new int[first.GetLength(0), first.GetLength(1)];
int x = -1;
for (int i = 0; i < first.GetLength(0); i++)
{
    for (int j = 0; j < first.GetLength(1); j++)
    {
        second[i, j] = string.IsNullOrWhiteSpace(first[i, j]) ? x : Convert.ToInt32(first[i, j]);
    }
}

{
{"2", " ", " ", " ", "1"},
{"2", " ", "4", "3", " "},
{" ", "2", " ", "1", " "},
{" ", "1", " ", "3", " "},
{"1", " ", " ", " ", " "}
};
int[，]second=新int[first.GetLength（0），first.GetLength（1）]；
int x=-1；
for（int i=0；i

现场示例：

Convert（请注意，当字符串=

“

”时，我将放置一个

0

）：

int[，]second=newint[first.GetLength（0），first.GetLength（1）]；
for（int j=0；j

假设X=-1：

private static int[,] ConvertToIntArray(string[,] strArr)
{
    int rowCount = strArr.GetLength(dimension: 0);
    int colCount = strArr.GetLength(dimension: 1);

    int[,] result = new int[rowCount, colCount];
    for (int r = 0; r < rowCount; r++)
    {
        for (int c = 0; c < colCount; c++)
        {
            int value;
            result[r, c] = int.TryParse(strArr[r, c], out value) ? value : -1;
        }
    }
    return result;
}

private static int[，]ConvertToIntArray（字符串[，]strArr）
{
int rowCount=strArr.GetLength（维度：0）；
int colCount=strArr.GetLength（维度：1）；
int[，]结果=新的int[rowCount，colCount]；
对于（int r=0；r

我试图用循环解决这个问题，但我无法做到，因为X应该是空字符串

“

那么，我不明白你想做什么。如果

X

不是

int

，则不能将其放入

int

数组中。

int[,] second = new int[first.GetLength(0), first.GetLength(1)];

for (int j = 0; j < first.GetLength(0); j++)    
{
    for (int i = 0; i < first.GetLength(1); i++)
    {
        int number;
        bool ok = int.TryParse(first[j, i], out number);
        if (ok)
        {
            second[j, i] = number;
        }
        else
        {
            second[j, i] = 0;
        }
    }
}

private static int[,] ConvertToIntArray(string[,] strArr)
{
    int rowCount = strArr.GetLength(dimension: 0);
    int colCount = strArr.GetLength(dimension: 1);

    int[,] result = new int[rowCount, colCount];
    for (int r = 0; r < rowCount; r++)
    {
        for (int c = 0; c < colCount; c++)
        {
            int value;
            result[r, c] = int.TryParse(strArr[r, c], out value) ? value : -1;
        }
    }
    return result;
}
