string FeeId = grdvw.Rows[index].Cells[0].Text;
这是检索所选行中单元格内容的正确方法吗?如果我使用它,我就没有价值。所以,请建议最佳方式。

是的,这是一种方法,您也可以这样做:
string FeeId = grdvw.Rows[index].Cells[0].Value;
另外,如果你想从所有行中获取值,你可以像这样迭代Datagridview:
foreach (DataGridViewRow row in grdvw.Rows)
{
string column0 = row.Cells[0].Value;
string column1 = row.Cells[1].Value;
//More code here
}

我尝试时获得了价值。以下是我在运行时添加行和列的示例:
public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable();
DataColumn dCol1 = new DataColumn("Col1", typeof(System.String));
DataColumn dCol2 = new DataColumn("Col2", typeof(System.String));
dt.Columns.Add(dCol1);
dt.Columns.Add(dCol2);
for (int i = 0; i < 2; i++)
{
DataRow row1 = dt.NewRow();
row1["Col1"] = "One";
row1["Col2"] = "Two";
dt.Rows.Add(row1);
}
foreach (DataColumn col in dt.Columns)
{
BoundField bField = new BoundField();
bField.DataField = col.ColumnName;
bField.HeaderText = col.ColumnName;
GridView1.Columns.Add(bField);
}
GridView1.DataSource = dt;
//Bind the datatable with the GridView.
GridView1.DataBind();
string str = GridView1.Rows[0].Cells[0].Text;
}
}

public void testMethod() {
String myArray[] = new String [] { "cook", null, "chef", "baker", null, null, "butcher", null, "distiller" };
for (int i = 0, count = 0; i < myArray.length; i++) {
if (myArray[i] != null)
System.out.println((++count) + ". " + myArray[i]);
}
}
如果我们这样使用,我们就会得到答案
