Question

I’ve a table in a DataSet and I want to search for a row in this Table using a unique key.

My question is : Is there any method that allows me to find this row without using loops ?

This is the code I wrote using the forech loop :

foreach (var myRow in myClass.ds.Tables["Editeur"].AsEnumerable())
{
     if (newKeyWordAEditeurName == myRow[1] as String)
         id_Editeur_Editeur = (int)myRow[0];
}

Sure. You have the Select method off of a DataTable. GEt the table from your DataSet, and use Select to snag it.

void Demo(DataSet ds)
{
    DataTable dt = ds.Tables[0]; // refer to your table of interest within the DataSet

    dt.Select("Field = 1"); // replace with your criteria as appropriate
}
