/// <returns>DataTable</returns>
public static DataTable CreateSelfDataTable(String[] sList)
{
DataTable _dtSelf = new DataTable(); foreach (String s in sList)
{
_dtSelf.Columns.Add(s);
}
_dtSelf.AcceptChanges(); return _dtSelf;
} View Code
3、临时创建一个表
private static DataTable CreatTable(){DataTable dtSource = new DataTable();dtSource.Columns.Add("NAME", typeof(string));dtSource.Columns.Add("DisMembers", typeof(string));//一百万行数据for (int i = 0; i < 1000000; i++){DataRow dr = dtSource.NewRow();dr["NAME"] = i;dr["DisMembers"] = i;dtSource.Rows.Add(dr);}dtSource.AcceptChanges();return dtSource;}View Code
