一種方法是，
您可以遍歷數據集中數據表中的行，然后只從每行的列中取出 100 個拆分詞，然后從拆分詞中生成字符串并將其綁定到同一列
該代碼未經測試，但您可以使用如下所示的代碼，
DataSet ds = new DataSet();
adp.Fill(ds);
foreach (DataRow row in ds.Tables[0].Rows)
{
row["itemdescription"] = string.Join(" ", Convert.ToString(row["itemdescription"]).Split(new char[] { ' ' }).Take(100));
}
ds.Tables[0].AcceptChanges();
DataList1.DataSource = ds;
DataList1.DataBind();
