DataRow[] rows = Dataset1.Tables[0].Select("Location_Name IN (" + Selected_locations + ")");
DataRow NewRow;

foreach (DataRow row in rows)
{
NewRow = NewTB.NewRow();
NewRow["Name"] = row["Name"];
NewRow["Reg_Date"] = row["Reg_Date"];
NewRow["Location_Name"] = row["Location_Name"];
NewRow["CityID"] = row["CityID"];
NewRow["LocationID"] = row["LocationID"];
NewRow["Reg_For"] = row["Reg_For"];
NewTB.Rows.Add(NewRow);
}

i have a more then one location for search. I can use this code..but there is a error on that select query….How to solve this?

DataRow[] rows = Dataset1.Tables[0].Select("Location_Name IN (" + Selected_locations + ")");
DataRow NewRow;

NewTB.Columns.Add("Name", typeof(string));
NewTB.Columns.Add("Reg_Date", typeof(DateTime));
NewTB.Columns.Add("Location_Name", typeof(string));
NewTB.Columns.Add("CityID", typeof(string));
NewTB.Columns.Add("LocationID", typeof(string));
NewTB.Columns.Add("Reg_For", typeof(string));

foreach (DataRow row in rows)
{
NewRow = NewTB.NewRow();
NewRow["Name"] = row["Name"];
NewRow["Reg_Date"] = row["Reg_Date"];
NewRow["Location_Name"] = row["Location_Name"];
NewRow["CityID"] = row["CityID"];
NewRow["LocationID"] = row["LocationID"];
NewRow["Reg_For"] = row["Reg_For"];

I have written a demo code for you just get the idea here, ANd check your actual data type where i have mentioned like string, datetime,int...
Just check your way
But it should like this

C#

var filterdata = (from f in dataset1.Tables[0].AsEnumerable()
                          where f.Field<string>("Location") == "India"
                          select new
                          {
                              Name = f.Field<string>("Name"),
                              Reg_Date = f.Field<DateTime>("Reg_Date"),
                              CityID = f.Field<int>("CityID"),
                              LocationID = f.Field<int>("LocationID"),
                              LocationName = f.Field<string>("LocationName"),
                              Reg_For = f.Field<string>("Reg_For")
                          }).ToList();
        foreach (var item in filterdata)
        {
            DataRow row = new DataRow();
            row["Name"] = item.Name;
            row["Reg_Date"] = item.Reg_Date;
            row["CityID"] = item.CityID;
            row["LocationID"] = item.LocationID;
            row["LocationName"] = item.LocationName;
            row["Reg_For"] = item.Reg_For;
            dataset2.Tables[0].Rows.Add(row);
        }

This would be easy if you will use this.

C#

DataTable table1 = new DataTable("Registration");
      table1.Columns.Add("Location");
      table1.Columns.Add("Id");
      table1.Rows.Add("Loc1", 1);
      table1.Rows.Add("Loc2", 2);
      table1.Rows.Add("Loc3", 3);
      table1.Rows.Add("Loc1", 4);
      table1.Rows.Add("Loc4", 5);
      table1.Rows.Add("Loc1", 6);
      table1.Rows.Add("Loc1", 7);
      table1.Rows.Add("Loc5", 8);


      DataTable table2 = new DataTable("Registration1");
      table2.Columns.Add("Location");
      table2.Columns.Add("id");

      DataSet Dset = new DataSet("DSET1");
      DataSet Dset1 = new DataSet("DSET2");
      Dset.Tables.Add(table1);

      if (Dset.Tables[0].Rows.Count > 0)
      {
          for (int i = 0; i < Dset.Tables[0].Rows.Count; i++)
          {
              DataRow dr = Dset.Tables[0].Rows[i];
              if (dr["Location"].ToString() == "Loc1")
              {
                  table2.Rows.Add(dr["Location"].ToString(),dr["Id"].ToString());


              }
          }
          Dset1.Tables.Add(table2);
      }

Best of luck.

Try this

C#

var query = from C in dataSet.Table["tablename"].AsEnumerable()
                        where C["Location"].ToString() == "USA"
                        select new {Location=C.Field<string>("Location"),Name=C.Field<string>("Name")};
           
            DataTable dataTable = new DataTable();
            DataRow dr = dataTable .NewRow();
                foreach(DataRow row in query)
                {
                    dr[0] = row.ItemArray[1].ToString();
                    dr[1] = row.ItemArray[2].ToString();
                    dataTable .Rows.Add(dr);
                }</string></string>

C#

DataSet Newdataset=new DataSet();
Newdataset.Tables.Add(dataTable );

Solution 1

For Filter Data in Data Set Use Select Method for Filtering data, it Returns Datarows.
You can now add these datarows into new dataset.
