Possible DuplicateNET - Convert Generic Collection to DataTable i want to convert list datatype to datatype. wrote the function

Dim list As List(Of DataRow) = dt.AsEnumerable().ToList()When I compile I get the error: 'AsEnumerable' is not a member of 'System.Data.DataTable'.I added Imports system.data.datatableextensions to the file..This code works when I run it on a asp.net project But when I use the same code in Website it returns the above error..Can anyone help solve this error.
I have a function and I am getting an error message. I need to convert my DataTable to an array and be able to access each line individually. This is the error message: Operator '-' is not defined for types 'System.Data.DataRowCollection' and 'Integer'.
I have a web service that is running and it shows a list of employees with their information. I created the web service with the following code:
[Code]....
The problem is 'Null' values in the datatable don't show up as empty tags in the XML so when I read the XML from the web service this is no consistency. Is there a way to show the tags even when the fields are null in the datatable or is there a better way to accomplish what I need. I'm reading this web service from a silverlight application with the following code (this application works but, it doesn't show all the employees as it skips over when no tag is present):
In my aspx page I have a HTML inputfile type which allows user to browse for a spreadsheet.Once the user choses the file to upload I want to read the content of the spreadsheet and store the content into mysql database table. I am using the following code to read the content of the uploaded file and convert it into a datatable in order into insert it into database table.
if (filMyFile.PostedFile != null) { // Get a reference to PostedFile object HttpPostedFile myFile = filMyFile.PostedFile; // Get size of uploaded file int nFileLen = myFile.ContentLength; // make sure the size of the file is > 0 if (nFileLen > 0) { // Allocate a buffer for reading of the file byte[] myData = new byte[nFileLen]; // Read uploaded file from the Stream myFile.InputStream.Read(myData, 0, nFileLen);...................................
I have a relatively simple Listview that suddenly needs (due to new requirements) to have it's 'layout' extracted to a DataTable so that a common routine can convert it to an Excel spreadsheet for export purposes.
The ItemTemplate is just a series of Table Rows with some text, data-bound labels and textboxes with validators in the cells.
Usually, when trying to pull out a particular value (like what was entered into a text box), I use the ListViewItem's .FindControl method.
For Each objItem As ListViewItem In lvwOptions.Items Dim objTextHrsLabor As TextBox = CType(objItem.FindControl("txtHrsOptByLabor"), TextBox) decHours = CDec(objTextHrsLabor.Text) Next
In this case, however, I'm trying to take all the data displayed - all the 'rows and columns' of the table that was created.
Inside the ForEach / Next loop of ListViewItems, I started a ForEach/Next loop of Controls for each instance's controls but I got some really strange results returned (like controls that had a couple of table cells in them).
I get the sense I'm headed in the wrong direction. All I want is for the nicely-formatted 5-line, 6 column table to be converted to a 5-line, 6-column data table.
We are using WCF and ADO.NET entity framework in our ASP.NET 4.0 application. we are using Entity Framework in our WCF service to execute a storedprocedure and return the results.
[WebGet] public List<Cs_MT> GetSearchResult(string emailId, string localTitle, string colorGrouping) {[code]....
We are calling the WCF service from our client application and get the results as IEnumerable
this is the web method I'm using to convert my DataTable into JSON string:
[Code]....
But I'm not sure this is as good and as fast as it should be. I am sending to client side a JSON string format, but I think maybe there is a better way of doing this. I know there is JSON.NET
but I didn't see there any converting for DataTables.
I'm having a problem with reading a string from sqlserver database and use it as the text of a label,
getDescTableAdapter gd = new getDescTableAdapter(); Label2.Text = Convert.ToString(gd.GetDesc(pid));
what i get in the form is: getDesc ! everything is right in the dataset and if i bind it to a gridview it works fine but when i convert it to string it seems it converts the table adaptor's name instead of the value.ance
