How to obtain the value of DataRow []

This article describes how to obtain the value of DataRow []. For more information, see

First, DataRow [] dr = dt. Select ("t1 = 'A'"); the result is an array. You only need to loop through this array.

The Code is as follows:

String x = "";

If (dr. Length> 0)

{

Foreach (DataRow drN in dr)

{

X + = drN ["t2"]; // cyclically obtain the values of column t2 after filtering conditions.

}

}

 

Note that the values of the first row can also be obtained as follows: to obtain the first value after filtering, you can use the following sentence to obtain

String x = dr [0] ["t2"]. Tostring (); // obtain the value of the t2 field in the first row after filtering.
