Hi Team,

I know this is silly but i just want to use this kind of logic in one of the modules.

So I have a table in a datatable **DTTest** like shown below:-

Name | Age |
---|---|

Robot | 1 |

Robot | 23 |

UiPath | 4 |

Temp | 5 |

Yes | 67 |

And I wanted to loop through the dt such that if Nth row and (N-1) row data for Name matches then perform **task ABC**. Whereas If is not not matching, perform **XYZ Task**.

I was easily able to perform this logic.

MY LOGIC:

for each row in DTTest:

if dtTest.Rows(index).Item(“Name”).ToString = dtTest.Rows(index-1).Item(“Name”).ToString

(perform ABC)

else (perform XYZ)

My problem: While this logic is working smoothly, I am getting index out of range error when we talk about the first row case ie (index=0) is being compared with (index - ‘-1’), which obviously goes out of range with respect to DT range.

Like if it is 1st row (index=0), then dont care about previous row

Please help me create a logic such that it handles the 1st row case too in my logic.

Thanks and Regards,
