将值从 datagridview 复制到二维字符串 C#

Question

我有一个二维变量，如下所示：

  string[] Dimension = new string[]
        {
                        "+-----+", // -----> X     /\Y
                        "|XXXXX|",
                        "|XXXXX|",
                        "|XXXXX|",
                        "|XXXXX|",
                        "|XXXXX|",
                        "+-----+",
        };

其次，我有 datagridview，其中有 6 行 + 6 列。 datagridview 的代码如下：

//Adding columns to datagridview
dataGridView1.Columns.Add("X0", "X0");
dataGridView1.Columns.Add("X1", "X1");
dataGridView1.Columns.Add("X2", "X2");
dataGridView1.Columns.Add("X3", "X3");
dataGridView1.Columns.Add("X4", "X4");
dataGridView1.Columns.Add("X5", "X5");

//Adding rows to datagridview  
dataGridView1.Rows.Add("Y0");
dataGridView1.Rows.Add("Y1");
dataGridView1.Rows.Add("Y2");
dataGridView1.Rows.Add("Y3");
dataGridView1.Rows.Add("Y4");
dataGridView1.Rows.Add("Y5");

//Adding values to datagridview.    
dataGridView1.Rows[1].Cells[1].Value = "X";
dataGridView1.Rows[2].Cells[1].Value = "X";
dataGridView1.Rows[2].Cells[2].Value = "X";
dataGridView1.Rows[1].Cells[2].Value = "X";
dataGridView1.Rows[3].Cells[3].Value = "X";
dataGridView1.Rows[4].Cells[3].Value = "X";
dataGridView1.Rows[4].Cells[4].Value = "X";
dataGridView1.Rows[3].Cells[5].Value = "X";

添加此值后，它在 winforms 中显示如下：

如何将值从 datagridview 转换（复制）到名为 Dimension 的字符串？

新字符串应该如下所示：

 string[] map = new string[]
        {
                        "+-----+", // -----> X     /\Y
                        "|XX   |",
                        "|XX   |",
                        "|  X X|",
                        "|  XX |",
                        "|     |",
                        "+-----+",
        };

有可能吗？把这个 "X" 放在里面才能得到这个结果？

Answer 1

所以基本上您会使用 2 个 for 循环查看数据网格视图 Columns 和 Rows。

1) 创建新地图：

string[] map = new string[dataGridView1.Rows.Count+1];
// give it a header
map[0] = "+" + new string('-', dataGridView1.Columns.Count - 1) + "+";

使用 StringBuilder 您可以为每个 line/row 构造一个取决于网格中的值的字符串。

for (int i = 1; i < dataGridView1.Rows.Count; i++)
{
    StringBuilder sb = new StringBuilder();
    sb.Append("|"); // frame left border
    for (int j = 1; j < dataGridView1.Columns.Count; j++)
    {
        // try to get the value            
        string value = dataGridView1.Rows[i].Cells[j].Value?.ToString();
        // if there is no value => take a space otherwise take the value
        value = string.IsNullOrEmpty(value) ? " " : value;
        // plug it into your string builder
        sb.Append(value);
    }

    sb.Append("|");  // frame right border
    // lunge the finished string into the array
    map[i] = sb.ToString();
}
// close the frame
map[dataGridView1.Rows.Count] = "+" + new string('-', dataGridView1.Columns.Count - 1) + "+";
Console.WriteLine(string.Join(Environment.NewLine, map));

控制台中的结果输出如下所示：

+-----+
|XX   |
|XX   |
|  X X|
|  XX |
|     |
|     |
+-----+
