You use Visual Studio .NET to develop a Windows-based application Your application will display customer order information from a Microsoft SQL Server database The

4、orders will be displayed on a Windows Form that includes a DataGrid control named DataGridl. DataGridl is bound to a DataView object. Users will be able to edit order information directly in DataGridl. You must give users the option of displaying only edited customer orders and updated values in Dat

5、aGridl What should you do?A: Set the RowStateFilter property of the DataView object to DataViewRowState.ModifiedOriginaLB: Set the RowStateFilter property of the DataView object to DataViewRowState.ModifiedCurrent.C: Set the RowFilter property of the DataView object to DataViewRowState.ModifiedOrigi

6、naLD: Set the RowFilter property of the DataView object to DataViewRowState.ModifiedCurrent 7. Another developer in your company uses Visual Studio NET to create a component named MyComponent. You deploy MyComponent to a server When you execute MyComponent, you receive the following error message: ,

7、fSystem.Security.Policy.PolicyException: Failed to acquire required permissions.v As quickly as possible, you need to discover which permissions are required by MyComponent. What should you do?A: Request the source code from the developer who created MyComponent. Examine the source code to find the

8、required permissions.B: Run the Microsoft CLR Debugger (DbgCLR.exe) on the server to view the permissions requested by the application at run time.C: Run the Runtime Debugger (Cordbg.exe) on the server to view the permissions requested by the application at run time.D: Run the Permissions View tool

9、(Permview.exe) on the server to view the permissions required by MyComponent.E: Run the MSIL Disassembler (Ildasm.exe) on the server to view permission requests by MyComponent that were denied.8. You use Visual Studio .NET to create an application. Your application contains two classes, Region and C

10、ity, which are defined in the following code segment. (Line numbers are included for reference only.)01 public class Region 02 public virtual void CalculateTax() 03/ Code to calculate tax goes here.04 05 06 public class City:Region 07 public override void CalculateTax() 08/ Insert new code.09 10 You

11、 need to add code to the CalculateTax method of the City class to call the CalculateTax method of the Region class. Which code segment should you add on line 08?A: CalculateTax();B: this.CalculateTax();C: base.CalculateTax();D: Region r = new Region();r.CalculateTax();9. You use Visual Studio .NET t

12、o create an application that uses an assembly. The assembly will reside on the client computer when the application is installed. You must ensure that any future applications installed on the same computer can access the assembly. Which two actions should you take? (Each correct answer presents part

13、 of the solution. Choose two.)A:Use XCOPY to install the assembly in the global assembly cache.B:Use XCOPY to install the assembly in the WindowsAssembly folder.C:Create a strong name for the assembly.D:Precompile the assembly by using the Native Image Generator (Ngen.exe). E:Modify the application

14、configuration file to include the assembly.F:Use a deployment project to install the assembly in the global assembly cache. G:Use a deployment project to install the assembly in the WindowsSystem32 folder.10. You use Visual Studio .NET to create a component named Request. This component includes a m

15、ethod named AcceptRequest, which tries to process new user requests for services. AcceptRequest calls a private function named Validate.You must ensure that any exceptions encountered by Validate are bubbled up to the parent form of Request. The parent form will then be responsible for handling the

16、exceptions. You want to accomplish this goal by writing the minimum amount of code.What should you do?A: Use the following code segment in AcceptRequest: this.Validate();B: Use the following code segment in AcceptRequest:try this.Validate();catch(Exception ex) throw ex;C: Use the following code segm

17、ent in AcceptRequest:try this.Validate();catch(Exception ex) throw new Exception(Exception in AcceptRequest, ex);D: Create a custom Exception class named RequestException by using the following code segment:public class RequestException:ApplicationException public RequestException():base() public Re

18、questException(string message):base(message) public RequestException(string message, Exception inner):base(message, inner) In addition, use the following code segment in AcceptRequest: try this.Validate(); catch(Exception ex) throw new RequestException(Exception in AcceptRequest, ex);三簡(jiǎn)答題：11 ：.NET 中主要有那幾種類型的控件，各有什 么區(qū)別？列舉一些常用控件的屬性和事件？12 ：.NET 中主要的類庫(kù)有那些，以及在實(shí)際中 的使用方向？13 ：介紹 ADO.NET 中幾個(gè)數(shù)據(jù)庫(kù)處理的核心 對(duì)象，以及各自的優(yōu)缺點(diǎn)。14 ：try 里有一個(gè) return 語(yǔ)句，那么緊跟在 這個(gè) try 后的 finally 里的 code 會(huì)不會(huì)被執(zhí) 行，什么時(shí)候被執(zhí)行，在 return 前還是后 ?15：C#中主要有那幾種循環(huán)語(yǔ)句，相互之間的 區(qū)別？16：軟件開發(fā)過程一般有幾個(gè)階段？每個(gè)階段的 作用
