Cannot implicitly convert type 'System.Collections.Generic.IEnumerable<string>' to 'string' OK I am fairly new to LINQ, but I am starting to get the hang of it. So here is the of my code that bugs:
[Code]....
And it returns this error, on the second line for p:
Cannot implicitly convert type 'System.Collections.Generic.IEnumerable<string>' to 'string'
If I have below code, how to make it work as it has below compile error:
Error: cannot implicitly convert type 'System.Linq.Iqueryable<system.data.DataSet> to 'System.Data.Dateset'. An explicit conversion exists.
public DataSet GetProductList() { using (var sdatabase = new DatabaseDataContext()) { IQueryable<DataSet> result = wmsdatabase.ExecuteQuery<DataSet>(@"SELECT productid, productname from product group by productid, productname").AsQueryable(); return result; // Compile error here } }
I want to log all errors happened in my App to sql db. I'm passing all exception properties like (ex.Message, ex.Source, ex.StackTrace, ex.TargetSite and ex.InnerException) to stored procedure.
The problem is that when I try to pass the ex.InnerException as string to stored procedure I got this error:
Cannot implicitly convert type 'System.Exception' to 'string'
I tried ex.InnerException.ToString() and Convert.ToString (ex.InnerException) but no success.
I have a datalist which querys the database and pulls the data ApplicantID, date, and testimonial into the datalist. I now want to get the username from the ApplicantID. Im using TLists to do this but on the line ApplicantDetails = JustClick.DAL.DataRepository.ApplicantProvider.GetByApplicantID(ApplicantID);
im getting the error cannot implicitly convert type on datalist can anyone help as to why and how I can fix this cheers. The code im using is below
Cannot implicitly convert type 'System.Collections.Generic.IEnumerable' to 'hcgames.ObjectClasses.ShoppingCart.ShoppingCartCartAddon'. An explicit conversion exists (are you missing a cast?)
From this query
ShoppingCartItems items = Cart.GetAllItems(); ShoppingCartCartAddons addons = Cart.GetAllAddons(); var stuff = from x in items select new ShoppingCartItem() { ProductID = x.ProductID, Quantity = x.Quantity, Name = x.Name, Price = x.Price, Weight = x.Weight, Addons = (from y in addons where y.ShoppingCartItemID == x.ID select y) };
I have been messing about with this for hours surely this should be an easy task ....... I have a stored procedured that creates a invoice on a Quotetable one of the parameters is a output parameter Invoice Number this is passed to a label. (Label1) This works great.
I then need to add items to the invoice on a item table so my next stored procedure should take the value of Label1 and update the foreign key quotenumber on the itemtable with the value from label1.
On the aspx page I have a small section for a gridview which shows the current quote with however many items on it using the control
[Code]....
On the ASP page the control for @Quotenumber = Label1 but I get the following error
'Conversion failed when converting the nvarchar value 'Label' to data type int.'
In Visual Studio 2008 I have a Class Library project (called Media) to which I added a Web Reference (not a Service Reference) to a third-party web service (wsdl). In the Class Library project a proxy class is created for using the service along with several classes for the types used in that service.
I also have a second Class Library (called Sync) that references the first one. And then I have a Web Site project that references the second class library. All of this is .NET 3.5
So Web Site > Class Library (Sync) > Class Library with web service reference (Media)
I want to step into the generated code, so I fire up the web site in IIS 7.5 and trigger the call to a method in the second class library (Sync) that in turn should call the web service proxy. I was fully expecting to hit the breakpoint, but instead got an exception:
Unable to generate a temporary class(result=1). error CS0029: Cannotimplicitly convert type Media.WebService.multiValuedAttribute to Media.WebService.multiValuedAttribute[]
Why is ASP.NET trying to generate a temporary class? Don't I already have the generated class from the first Class Library (Media)?
I am trying to get text box values into a database from a asp.net form. In my SQL server database I have defined the field emailID as nvarchar(50) and I still get the error messageconversion failed when converting the varchar value abcd@efg.com to type int" I am not trying to convert it int so my guess is SQL server is doing some kind of implicit conversion.
I have a gridview which I'm trying to get the display of phonenumbers listed in a certain display format; (xxx) xxx-xxxx.If I have the code such as this, it displays the unformatted phone number and (000) 000-0000 for the null items.
I seem to be having issues with posting forms with DropDownLists. I've looked all over the net and tried various solutions, but none seem to work for me.
I'm getting the following error: The parameter conversion from type 'System.String' to type 'Models.Organization' failed because no type converter can convert between these types.
Here's my ViewModel:
[Code]....
Here's my controller:
[Code]....
The objects are generated by ADO.NET Entity Framework. Organizations is its own object, but also a property of Profile (each user belongs to one organization). Now I understand what the error message is saying, just not sure how else I'm supposed to do this.
I have this method which does not build, it errors with the message:
Cannot implicitly convert type 'System.Web.HttpPostedFile' to 'System.Web.HttpPostedFileBase' I really need this to be of type HttpPostedFileBase instead of HttpPostedFile, I have tried boxing and it does not work: foreach (string inputTagName in HttpContext.Current.Request.Files) { HttpPostedFileBase filebase =HttpContext.Current.Request.Files[inputTagName]; if (filebase.ContentLength > 0) { if (filebase.ContentType.Contains("image/")) { SaveNonAutoExtractedThumbnails(doc, filebase); } } }
This code works somewhat, but it won't place all of the text into the textbox.. If I change a few things I get an error where I highlighted the code in red. Conversion from string "" to type 'Double' is not valid. But the code works, like I said somewhat, as you see it, it just doesn't load all of the text to the text box.555632.txt
