ADO.NET :: Use ArrayList Elements As Parameter For Linq Where Condition?
Sep 11, 2010
I have a list of customer Id's as the result of a Linq Query named "localCustomers" which contains 100 or so Customer ID's.I'm would like use this list to query and access customers' info on the whole group. Been searching on how to do this but no luck. It's easy enough with one customer ID, but how do I do it with an arrayList as the parameter? Here's my latest attempt but it's not working.
I need to initiate an Array to hold 100 integers. Then, by user click, a random number 1-100 is generated, and subtracted from the list. In the next call, the next random number will be subtracted from the 99 numbers left, next from the 98 numbers and so on. I need to do this with AJAX and if needed a webservice. The reason I am asking here is because I am confused...Where shall I instanciate the array and how do I keep track of the removed numbers?
string strCondition = "FirstName=='abc'" from p in People.Where(strCondition) select p
In our architecture we are usign both Linq-Sql as well Linq-Entity. So please give some thoughts wehter it is possible or not and is there any way to perform this?
I have a array of ArrayList as shown below:ArrayList[] m;My web service method takes this type as parameter.How can I send it to web service?When I do so the Web Service changes my array of ArrayList to Object[][]!
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
This arrayList produced by the Linq query returns data pairs of an ID and count. I would like to keep pairs that have a high enough count. For example, keep all that have a count of 5 and higher so if the arraylist contains:
userID Count
1 10 2 9 3 9 4 3 5 1
the remaining data in the arraylist would be userId 1,2, and 3 (with their counts). How can I do this?
I am trying to write a linq query that will retrieve all the ID's from any asp tag. Also, the query needs to group everything together alphabetically. So for the example above, the linq query should return "lbl1", followed by "lbl2", followed by "txt1", and finally "txt2". Notice it did not grab the "bodyID" because it was not part of an ASP.NET tag. Is there an easy way to do this? I am using C#, by the way.
I'm new on LINQ and I'm searching the best way to do this:
I have an object client that has a list of subscriptions. Subcription has a boolean attribute "Active". Now I want load only the clients with list > 0 and subscription active.
The question is: If a client has 3 subscriptions, but only 2 are active, how can I load only the latters ? I tried in this way:
[Code]....
The query selects clients that has at least one subscription active, but viewing the results, it loads also subscriptions not active of the same client.
I have LINQ result, and I have List.I want to do Where() on the LINQ and to REMOVE all the matching strings from the List.I get errors of:Local sequence cannot be used in LINQ to SQL implementations of query operators except the Contains operato
I am developing asp.net mobile application. I am using XML as a database. I am querying on the XML to access the required elements & attributes by using LINQ to XML in .net. I have the follwing part in my XML file.
[code]....
The similar logic I need for the above defined XML part. In the above XML I want to write the LINQ to XML query which can access the NAME attribute of the 'VALVE' node (<VALVE NAME="PWV">), then it should access the text between 'DISPLAY-NODE' (<DISPLAY-NAME> Production Master Valve </DISPLAY-NAME>), & then it should access the all the attributes of the 'COMMAND' node dynamically ( <COMMANDS USE-TEMPLATE="TRUE" TEAMPLATE-NAME="ValveCommands.xml"></COMMANDS>). All these I want dynamically without explicitly specifying the name of the child node as well as name of their attributes ( similar to the way I written the above query ) Can we write such a code by using LINQ to XML ? It will be better if we can write code for above issue in a single logic ( similar to the way I written the above query ).
i want to create a arraylist which will able to store user info like (username,machineIP,port ) for each user in the list & retrive this data when needed . any one tell me how i can do it or any alternative way without database or xml file.
I have...a dynamic populated select box several input boxes a submit button form fields are loaded initially using cookies several dynamic populated divs

The problem is that, how to return OUTPT value to dTtoal and the remaining. Because now it's show assigned values as 1, 2, 3, 4 resp. I mean the bold values.But, if I execute SP using EXEC then it works fine, shows result correctly.
know if the followin is supported in .net framework 4.0?I have a sql stored procedure with one of its parameter as Hierarchy data type( i suppose its a table valued parameter).. trying to drag this stored procedure onto my linq design studio is not being allowed?
I'm new to LINQ and C# but I have an xml file generated from a database table. Within the XML document is a element called "group", I would like to wrap all group elements with the element called "groups".
I always have this problem returning an out parameter from sql server using linq. So I have to use other means may be dataset. The following is the stored procedure: ALTER PROCEDURE [dbo].[InsertIntoTestProfile]
