假设您的工作表PR

然后您必须在按钮单击中查看此代码以获取更新
conn= new OleDbConnection();
conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=e:\PRTEXT.xls;Extended Properties=Excel 8.0";
conn.Open();
string xlsSheet = "PR$";
adap.UpdateCommand = new OleDbCommand("UPDATE [" + xlsSheet + "] SET FirstName = ?, LastName = ?, Age = ?" +
" WHERE FirstName = "+ ds.Tables[0].Rows[0][0], conn);
adap.UpdateCommand.Parameters.Add("@FirstName", OleDbType.Char, 255).SourceColumn = "FirstName";
adap.UpdateCommand.Parameters.Add("@LastName", OleDbType.Char, 255).SourceColumn = "LastName";
adap.UpdateCommand.Parameters.Add("@Age", OleDbType.Char, 255).SourceColumn = "Age";
//// Updates the first row
ds.Tables[0].Rows[0]["FirstName"] = "john";
ds.Tables[0].Rows[0]["LastName"] = "Statham";
ds.Tables[0].Rows[0]["Age"] = "55";
adap.Update(ds.Tables[0]);
conn.Close();
