Dataset Cell operations

1 dataset. Table [0]. Rows [I] [J]

Where I represents the number of I rows, and J represents the number of J Columns

2 dataset. Table [0]. Rows [I]. itemarray [J]

Where I represents the number of I rows, and J represents the number of J Columns

3 dataset. Tables [0]. Columns. Count

Retrieve the total number of columns in a table

4 dataset. Tables [0]. Rows. Count

Retrieve the total number of rows in the table

5 dataset. Tables [0]. Columns [I]. tostring ()

Retrieve the I column name of the table

Note: The calculation of rows and columns starts from 0.

========================================================== ================================

Dataset has taken the value from the database. Currently, dataset has
A B C
1 One
2 two 2
3 three 3
4 four 4

Can I implement the value of C equal to 2 and B?
In SQL, select B from temp_table where c = "2"

For (INT I = 0; I <dataset. Tables [0]. Rows. Count; I ++)
{
If (Dataset. Tables [0]. Rows [I] [2]. tostring (). Equals ("2 "))
{
String value = dataset. Tables [0]. Rows [I] [1]. tostring ();
}
}
The value of value is "two"
