Update column header

[SunnyJha]

I have a column called “Name” in a datatable variable, I want to update it to “FirstName”. How do I go about this? I found there’s no activity in UiPath to do this?
I followed the below steps-
Let’s say you have a DataTable variable named dt, and you want to update the column header from “OldColumnName” to “NewColumnName”. Here’s how you would configure the Assign activity and the Invoke Method activity:

• Assign Activity:
  • To: column (Create a new variable with this name of type System.Data.DataColumn)
  • Value: dt.Columns("OldColumnName")
• Invoke Method Activity:
  • Target Object: column
  • Method Name: SetColumnName
  • Parameters: "NewColumnName"

but there’s an error " datacolumn does not have a public instance method “SetColumnName”

I used this and it worked-

• First Assign activity:
  • To: column
  • Value: dt.Columns("OldColumnName")
• Second Assign activity:
  • To: column.ColumnName
  • Value: "NewColumnName"
