Find row in datatable with specific id

Question

I have two columns in a datatable:

ID, Calls. 

How do I find what the value of Calls is where ID = 5?

5 could be anynu

Answer 1

try this code

DataRow foundRow = FinalDt.Rows.Find(Value);

but set at lease one primary key

Answer 2

DataRow dataRow = dataTable.AsEnumerable().FirstOrDefault(r => Convert.ToInt32(r["ID"]) == 5);
if (dataRow != null)
{
    // code
}

If it is a typed DataSet:

MyDatasetType.MyDataTableRow dataRow = dataSet.MyDataTable.FirstOrDefault(r => r.ID == 5);
if (dataRow != null)
{
    // code
}
