我在表单上有一个datagridview1,它包含多少列和数据。在这里,我需要找到包含十进制值“0.04”的特定单元格(例如),单击按钮必须用数字值“0”替换。
我已经尝试过了,
private void button1_Click(object sender, EventArgs e)
{
string filterBy;
filterBy = "Stringtext Like '%" + 0.04 + "%'";
((DataTable)dataGridView1.DataSource).DefaultView.RowFilter = filterBy;
int rows = dataGridView1.Rows.Count;
for (int i = 0; i < rows-1; i++)
{
dataGridView1[2, i].Value = dataGridView1[2, i].Value.ToString().Replace(0.04, 0);
}
dataGridView1.Refresh();
}
没有用,任何人都可以帮忙..?
提前感谢..

我不会像你一样以艰难的方式去做。我就是这样做的:
private void button1_Click(object sender, EventArgs e)
{
int countColumn, intCell = -1, intRow = -1;
countColumn = dataGridView1.Columns.Count;
foreach (DataGridViewRow row in dataGridView1.Rows)
{
intRow++;
foreach (DataGridViewCell c in row.Cells)
{
//if (c.Value == null) { continue; }
if (c.Value?.ToString() != "0.04") { continue; }
intCell = +1;
dataGridView1.Rows[intRow].Cells[intCell].Value = "0";
if (intCell == countColumn)
{
intCell = -1;
}
}
}
}
