How to prevent insertions of duplicate record into datatable

Renjith R

foreach (Selected s1 in objlistCropped)
{
string strImg2 = s1.Image;
if (strImg1 == strImg2)
{
dtPreInstallation.Rows.Add(strImg2, s.strText);
}
}

strImg1 = Img1.Jpeg,
I need to restrict adding img1.jpeg again if its already there in datatable.
Thanks in Advance

dtPreInstallation.Select("Dtcolname = '" + strImg1+"'");
It will return array of DataRow so if count of element in array is greater than 0 then that string name is already present else you can add new row
0
