As shown below, I am doing a check to see if a certain value exists in a certain Datatable column, and the return value is stored in a variable of type Boolean.
I’ve checked by outputting the value to be searched, the Datatable, and the column name, and I’m pretty sure that the value to be searched exists in the corresponding column of the Datatable, and the return value should be True.
Dt_TDI_PL OK
column name: 科目 OK
search target: item_formula.ToString.Substring(1): OK
So I am wondering if there is something wrong with the following equation.
And I’ve tried all of the following methods, and they all return a false return value. I just couldn’t find where the problem was. Can someone please help me?
The Lookup Datatable activity can be used to check the value in particular column . it would return the index value etc . So if the value is less than 0 it can be considered as not there.
Thank you for your xaml file.
When I open this file, there is an error, cloud you tell me the missing activity name? so I can download this activity package. Thank you!!!
