I'm not experienced enough with the foreach statement to quite figure out what I'm doing wrong here.
I have data in ParamList (from SQL reporting services database)which I want to display in a GridView. as ParameterName and VAlue. I am able to retrieve the parameters but can't figure out how to read them into ArrayList (or whatever method you coud suggest) and then bind to grid. Final grid should be like this-
ParameterName ParameterValue
Year 1011
Number1 0011
Number2 0101
Number3 0201
Here is the code I'm trying to figure out-
Dim intCount As Integer
Dim strparam As String
Dim strparam1 As String
Dim varResult As Object
Dim ParamList as string
ParamList = "Year=1011&Number1=0011&Number2=0101&Number3=0201"
varResult = Split(ParamList, "&")
Dim arrList As New ArrayList()
'loop through array and retrieve parms
For intCount = 0 To UBound(varResult)
varParam = Split(varResult(intCount), "=")
strparam1 = UCase(varParam(0))
strparam = varParam(1)
arrList = ???
Next
'and then display tsi data into a grid.
GridViewParams.DataSource = arrList

I have a problem with assigning string array into Datarow. Firstly, i have created the object for string array and put 2 values in the array out of 100(whole size). How many values should be placed in the array dependds on a different, which i am not showing here, though.
Then i tried converting into DataRow. But it says. "object reference not set to an instance of an object"
DataRow dr = null;
string[] strconcat = new string[100];
dr["concat"] = strconcat[i];
Edit-- Actually i was trying put these string array values into dropdown (ddchooseadeal).

I am trying to use aspx pages as an email templates. There will likely be a bunch of objects on the page which will be used as replacements in the html. Because it's an aspx page I'll be able to use databinding, repeaters, etc. At run time, I want to be able to instantiate the aspx page from its path, pass in a bunch of properties, and then get the rendered result of the page and email it. This seems pretty straightforward from a asp.net website (maybe using BuildManager or Server.Execute.) However, I want to be able to use the same templates via a console application by just loading up a page object from its filepath. Is this possible?
