我想从DataGridView的一列中读取数据。我的DataGridView包含多列,但我只想读取其中一列的所有单元格。我使用以下代码读取了所有列:
foreach (DataGridViewColumn col in dataGridView1.Columns)
col.Name.ToString();
但是我想读取特定列中的所有单元格。

试一下
string data = string.Empty;
int indexOfYourColumn = 0;
foreach (DataGridViewRow row in dataGridView1.Rows)
data = row.Cells[indexOfYourColumn].Value;
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..
}
}
}
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循环
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循环
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);
}
foreach (var cell in col.Cells)
这个不行吗? - Nolonar
