如何从datagridview的一列中读取数据
本文关键字:一列 读取 数据 datagridview | 更新日期: 2023-09-27 18:00:19
我想从datagridview的一列中读取数据。我的数据网格视图包含许多列,但我想读取所有单元格,但只能读取一列。我使用以下代码阅读所有专栏:
foreach (DataGridViewColumn col in dataGridView1.Columns)
col.Name.ToString();
但我想读取特定列中的所有单元格。
试试这个
string data = string.Empty;
int indexOfYourColumn = 0;
foreach (DataGridViewRow row in dataGridView1.Rows)
data = row.Cells[indexOfYourColumn].Value;
也许这也有帮助。获取一个单元格:
string data = (string)DataGridView1[iCol, iRow].Value;
然后您可以简单地循环行和列。
文件。
尝试这个
foreach (DataGridViewRow row in dataGridView1.Rows)
{
foreach (DataGridViewCell cell in row.Cells)
{
if (cell.ColumnIndex == 0) //Set your Column Index
{
//DO your Stuff here..
}
}
}
或者另一种方式
foreach (DataGridViewColumn col in dataGridView1.Columns)
{
if (col.Name == "MyColName")
{
//DO your Stuff here..
}
}
获取点击单元格的值:
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
textBox1.Text = dataGridView1[e.ColumnIndex, e.RowIndex].Value.ToString();
}
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);
}
