If I understand you correctly, by passing the formula as a string will require the current class to be responsible for performing the parsing as well as whatever this class is meant to do with the result, this is probably bad object encapsulation.

...unless you are parsing text entries from a user or some other source (e.g. text input from a UI or file), writing formulas in strings and then evaluating them is bad design...

DataTable dataTable = new DataTable("MyTable");
dataTable.Columns.Add("Column1");

DataRow dataRow = dataTable.NewRow();
dataRow["Column1"] = "0";
dataTable.Rows.Add(dataRow);

DataRow[] foundRows = dataTable.Select("Column1 = 0");
Trace.Write(foundRows); // <- Count = 1

dt.Select("Status =1");

dataGridView1.DataSource = dtSelect("Status =1");

datagrid.DataSource = bindingSource1;
bindingsource1.DataSource = dt;
