DataTable如何删除特定行

[ishowing]

我希望把一个DataTable表中特定的部分不在页面上显示,就是说在显示前删除.如何删除DataTable中特定的行呢?
DataTable dt = newsBase.GetAllnews();
/*DataRow[] foundRow;
foundRow = dt.Select("catalogid = 0", "");
DataTable newTb = dt.Clone();
foreach (DataRow row in foundRow)
{
newTb.Rows.Remove(row);
}*/
dt.Columns.Remove("catalogid = 0");
GridView1.DataSource = dt;
GridView1.DataBind();

dt.Rows.RemoveAt(行号);

DataTable dt = newsBase.GetAllnews();
DataRow[] foundRow;
foundRow = dt.Select("catalogid = 0", "");
DataTable newTb = dt.Clone();
foreach (DataRow row in foundRow)
{
newTb.Rows.Remove(row);
}

GridView1.DataSource = newTb ;
GridView1.DataBind();

这样子不行吗？

楼上的方式
异常详细信息: System.IndexOutOfRangeException: 给定的 DataRow 不在当前的 DataRowCollection 中。
newTb.Rows.Remove(row);
这行报错~~

dt.Rows.RemoveAt(0);//删除1

你上面那段屏掉的那段
DataRow[] foundRow = dt.Select("catalogid = 0", "");
foreach (DataRow row in foundRow)
{
dt.Rows.Remove(row);
}

[ishowing]

DataTable dt = newsBase.GetAllnews();
DataRow[] foundRow;
foundRow = dt.Select("catalogid = 0", "");
DataTable newTb = dt.Clone();
foreach (DataRow row in foundRow)
{
newTb.Rows.Remove(row);
}

GridView1.DataSource = newTb ;
GridView1.DataBind();

异常详细信息: System.IndexOutOfRangeException: 给定的 DataRow 不在当前的 DataRowCollection 中。
newTb.Rows.Remove(row);
这行报错~~

DataTable dt = newsBase.GetAllnews();
DataRow[] foundRow;
foundRow = dt.Select("catalogid = 0", "");
foreach (DataRow row in foundRow)
{
dt.Rows.Remove(row);
}
GridView1.DataSource = dt;
GridView1.DataBind();

问题解决~~
没必要再去拷一遍dt~~
DataTable newTb = dt.Clone();
