Both of them contains 54 headers.
If there is a mismatch in headernames then BOT will throw Business exception

Hi Zara,
Try this
dt1.Columns(0).ToString=dt2.Columns(0).ToString
Hope it will work
tried…but its picking only first header name…i want to match all 54 with the another 54
then You have to use nested loop for this. Let me show
if u have any reusable code for this…pls share
@Zara
with following statement you will get the column names as list:
YourDataTableVar.Columns.Cast(Of DataColumn).Select(Function (x) x.ColumnName).toList
with the data set operations you can identify if its matching or not e.g. with intersect or except

Hello,
help me understand if the column headers don’t match then how to print the header of the data table from which we were comparing? in respect to the below screenshot I am looking for the column’s name of DT1 in the Else part.
lets find out the common rows:
dt1dt3Commons = dt1Cols.Intersect(dt3Cols).ToArray
lets find out the non common rows:
dt1Todt3Differences = dt1Cols.Except(dt1dt3Commons).ToArray
dt3Todt1Differences = dt3Cols.Except(dt1dt3Commons).ToArray
lets print it
“DT1 differs with: " + String.Join(”, " ,dt1Todt3Differences)
“DT3 differs with: " + String.Join(”, " ,dt3Todt1Differences)

Kindly note:
the check was organized in order to rely not on same datacolumn positions. Just findout the different columns based on its names.
For a check on name, position and same column count, we can do very fast with following:
