Question

我想从datagridview的一列读取数据。我的datagridview包含许多列，但我想读取所有单元格，但只读取一列。我使用以下代码阅读所有列：

foreach (DataGridViewColumn col in dataGridView1.Columns)
        col.Name.ToString();

但我想从特定列中读取所有单元格。

Answer 1

试试这个

string data = string.Empty;
int indexOfYourColumn = 0;
foreach (DataGridViewRow row in dataGridView1.Rows)
   data = row.Cells[indexOfYourColumn].Value;

Answer 2

也许这也有帮助。获得一个单元格：

string data = (string)DataGridView1[iCol, iRow].Value;

然后你可以简单地循环行和列。

Answer 3

试试这个

foreach (DataGridViewRow row in dataGridView1.Rows)
        {
            foreach (DataGridViewCell cell in row.Cells)
            {
                if (cell.ColumnIndex == 0) //Set your Column Index
                {
                //DO your Stuff here..
                }
            }
         }

或其他方式

       foreach (DataGridViewColumn col in dataGridView1.Columns)
            {
                if (col.Name == "MyColName")
                {
               //DO your Stuff here..
                }
            }

Answer 4

获取点击的单元格的值：

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
    {
        textBox1.Text = dataGridView1[e.ColumnIndex, e.RowIndex].Value.ToString();
    }

Answer 5

FOREACH LOOP

string data = string.Empty;
string data = string.Empty;
int indexOfYourColumn = 0;
int indexOfYourColumn = 0;
foreach (DataGridViewRow row in dataGridView1.Rows)
foreach (DataGridViewRow row in dataGridView1.Rows)
   data = row.Cells[indexOfYourColumn].Value;

FOR LOOP

using System.Collections;

string data = string.Empty;
int indexOfYourColumn = 0;

IList list = dataGridView1.Rows;

for (int i = 0; i < list.Count; i++)
{
  DataGridViewRow row = (DataGridViewRow)list[i];
   data = row.Cells[indexOfYourColumn].Value;
  data = Convert.ToDecimal(row.Cells[indexOfYourColumn].Value);
}
