How to get a datarow from a datable in C#?

I have a datatable which is having n no. of rows and each row has a unique field say ID.
Now I want to get a particular row for a specified ID.
eg. there are 5 rows in a datatable and the id's are
1,2,3,4 and 5 and if I want to select a row having ID = 4
What will be the code snippet for that?
Does anybody have any idea?
Thanks in advance,help me as soon as possible..Please

Solution 2

Since ID is a unique field then if it is set as the primary key of the DataTable then the DataRowCollection.Find method can be used as explained here
DataRowCollection.Find Method (Object)[^]
The Rows property of DataTable returns DataRowCollection, which can be used for Find method

Solution 4

use the following code

C#

DataTable dt; //intialize the table with data
           int [] sidx={4}; //put index you wish to find in array
           DataRow dr = dt.Rows.Find(sidx);

hope this helps

Best of luck.........
