Replace specific values of all columns of datatable

[rishiathawale]

Hi All,

Below is the datatable for reference, where I want to replace all Yes to No at once using linq.

I am aware about doing it for specific column but here I want to do it for all columns.

@ppr please look into scenario.

Thanks,
Rishi

Hi @rishiathawale ,

If it is a Direct Excel Update that you are Expecting, then we could also try the below case discussed :

How to replace blank cell with 0 using Excel activities

Hi Community!! I have an issue on replacing the blank cell with 0 by using Find/Replace value Excel activity but it’s not working. I don’t want to use the LinQ queries and also don’t want to use shortcut keys, Please suggest me how to do with Find/Replace value activity or any other way to do it.

You would require to Replace Type.Missing with the value you want to replace.

For the Datatable way, we could check the below Linq :

OutputDT = (From r In DT.AsEnumerable
Select ia = r.ItemArray.toList
Select ic = ia.ConvertAll(Function (e) if(e.ToString.Trim.ToLower.Equals("yes"),"no",e.ToString)).toArray()
Select OutputDT.Rows.Add(ic)).CopyToDataTable()

Where OutputDT is the Clone of the Input DT.

your statement is looking for res within a contains.
@supermanPunch gave a different one checking for Yes

[rishiathawale]

@ppr

Yes I am looking for res thats the keyword. it should replace ideally if its present.

[rishiathawale]

@Palaniyappan

not working, I guess this query is provided by @ppr in referred post.

[ppr (Peter Preuss)]

we saw

@rishiathawale

Below is the datatable for reference, where I want to replace all Yes to No at once using linq.

so it made sense when it was tried to look for yes

Just do a favor for us

• set a breakpoint (where dt_Final is already filled with the res values)
• debug and get paused
• use immediate panel and type in: dt_Final

share with us the outcome
