I want to search two string in datarows.For example;

string1="ex"
string2="ex2"
row1={'ex','ex2','ex3'....}---->True
row2={'ex3','ex1','ex2'....}---->True
row3={'ex2','ex5','ex6'....}---->False 

Each line must have a value of two strings.. For This,

for (counter = 0; counter < array.Count; counter++)
        {
            int index=0;
            ArrayList array3 = new ArrayList();
            array3 = Split(array[counter].ToString());
            foreach (DataRow row2 in data.Rows)
                foreach (object obje in row2.ItemArray)
                {
                    //Proceeds
                    }
                }
        }

I coding something.But I do not want to deal with pollution in the code... Is there an easy way to select method?

• c#
• linq

var result = data.AsEnumerable()
            .Where(r => r.ItemArray.Contains(string1) || r.ItemArray.Contains(string2))

Try to do something like this:

first define a DataView

DataView dv = new DataView(dt) where dt is a DataTable.

After apply RowFilter

dv.RowFilter = "CONTAINS(ColName, 'ex1') AND CONTAINS(ColName, 'ex2')".

Hope this helps.
