Hi,

Did you input as the following if your number of columns is 1.

new object[] {yourVariable}

Works like a charm:

So could it have to do with the datatypes you have in your array? (can you screenshot your variables as shown in my screenshot?)

But why mine is not working?Screenshot (4)

Hi,

Can you try to paste the following expression into the ArrayRow property?

new object[] {bitcoin_Price,lasthour_High,lasthour_Low}

If error occurs, please share its screenshot.

Hi
May be let’s do it other way

  1. Create a list variable named list_input in variable panel of type System.Collections.Generic.List(of String) with default value as New List(of String)

  2. Now use a ADD TO COLLECTIONS activity where in collections mention as List_input and in item mention the variable named bitcoin_Price.ToString

Use another activity with list variable name in collection but item as lasthour_High.ToString

And a final add to Collections with same collections variable and item as lasthour_Low.ToString

  1. Now use a ADD DATAROW activity Where in ARRAYROW property mention as list_input.ToArray() and in dt mention the DATATABLE name

Hope this would help you resolve this

Cheers @Althaf_nazeer_Nazeer

Hi,

Thank you for sharing.
This error shows these variables is not defined. (So, error have been changed.)
Is there same place at your previous screenshot? Can you share variable panel?

Or

To isolate cause, for now, can you try the following expression?

new object[] {}

Estoy aprendiendo de manera autodidacta UiPath. Intento usar aĂąadir fila de datos y me muestra error.
En Fila de Datos coloqué {“Mar”,“Montes”,22,“Femenino”} y me muestra error BC36915: No se puede realizar inferencia de un tipo de elemento porque es posible más de un tipo. Especificar el tipo de la matriz podría corregir este error. BC30311 El Valor de tipo ‘Object()’ no se puede convertir en ‘DataRow’. El Valor seleccionado es incompatible con el tipo de propiedad.

New object() {"Sea","Mountains",22,"Female"}
