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 anynumber, its just for example. Each row has a unique ID.

Answer 1

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
}

Answer 2

You can try with method select

DataRow[] rows = table.Select("ID = 7");
