Hello Experts

I am trying to store some pattern in the database table using the data from the function which returns the dataset.

I wanted to loop through all the records from this dataset and assign the value to the stringcollection variable.

Please can someone advise how I can go about looping through the rows I get from this dataset, once I get the column values I can then assign them to the string collection.

Please see the code below, hope someone may understand what I am trying to do here?

Thanks
S

Here is an example of looping through the dataset.


For i as integer = 0 to dSet.Tables(0).Rows.Count - 1
    str &= "Name: " & dSet.Tables(0).Rows(i).Item(0) & ", Address: " & dSet.Tables(0).Rows(i).Item(1) & VBCRLF
Next
