在 DataGridView 中显示二维数组 [英] Show 2d-array in DataGridView

问题描述

我有一个二维数组.我想在我的 DataGridView 中打印数组，但它抛出一个错误:

I have a 2D array. I want to print the array in my DataGridView but it throws an error:

[参数 OutOfRangeException 未处理]

[Argument OutOfRangeException was unhandled ]

这是我的代码

for (int j = 0; j < height; j++)
{
    for (int i = 0; i < width; i++)
    {
            dataGridView1[i, j].Value = state[i, j].h;    
            //state[i, j].h this is my array 
            dataGridView1[i, j].Style.BackColor pixelcolor[i,j];
            dataGridView1[i, j].Style.ForeColor = Color.Gold;
    }
}

推荐答案

正如评论所指出的，您应该关注行和单元格.您需要构建 DataGridView 列，然后逐个单元格填充每一行.

As comments have pointed out, you should focus on rows and cells. You need to build your DataGridView columns and then populate each row cell by cell.

数组的 width 应对应于 dgv 列，height 应对应于 dgv 行.举个简单的例子:

The width of your array should correspond to your dgv columns and the height to the dgv rows. Take the following as a simple example:

string[,] twoD = new string[,]
{
  {"row 0 col 0", "row 0 col 1", "row 0 col 2"},
  {"row 1 col 0", "row 1 col 1", "row 1 col 2"},
  {"row 2 col 0", "row 2 col 1", "row 2 col 2"},
  {"row 3 col 0", "row 3 col 1", "row 3 col 2"},
};

int height = twoD.GetLength(0);
int width = twoD.GetLength(1);

this.dataGridView1.ColumnCount = width;

for (int r = 0; r < height; r++)
{
  DataGridViewRow row = new DataGridViewRow();
  row.CreateCells(this.dataGridView1);

  for (int c = 0; c < width; c++)
  {
    row.Cells[c].Value = twoD[r, c];
  }

  this.dataGridView1.Rows.Add(row);
}
