C#中DataTable的使用，新手求助
本人是学习VC/MFC的，最近工作需要紧急修改一个C#程序，遇到各种不明白的地方，请大家指教。
先上代码：
for (int i = 0; i < count; i++)
{
DataRow dr;
dr = dt.NewRow();
dr[0] = true;//false
dr[1] = "0";
dr[2] = testfilelist.result[i].releaseDate;
dr[3] = testfilelist.result[i].latestVersion;
dr[4] = testfilelist.result[i].language;
dr[5] = "0";//FILESIZE
dr[6] = testfilelist.result[i].filename; //文件名称
dr[7] = testfilelist.result[i].ftpPath; //将文件名存这
dr[8] = testfilelist.result[i].downloadPath;
dt.Rows.Add(dr);
dt.AcceptChanges();
}
dtdistinct.Clear();
dtdistinct = dt.DefaultView.ToTable(true, new string[] { "Item", "SoftWare", "Date", "Index", "Filesize" });
DataColumn dataColumn1 = new DataColumn("Version", typeof(String));
dtdistinct.Columns.Add(dataColumn1);
dataColumn1 = new DataColumn("Language", typeof(String));
dtdistinct.Columns.Add(dataColumn1);
dataColumn1 = new DataColumn("filepath", typeof(String));
dtdistinct.Columns.Add(dataColumn1);
dataColumn1 = new DataColumn("downloadPath", typeof(String));
dtdistinct.Columns.Add(dataColumn1);
gridControl1.DataSource = dtdistinct;
//datarefreshgrid();
DataRow drOperate = dt.Rows[3];
drOperate.BeginEdit();
drOperate[0] = false;
drOperate.EndEdit();
