Q105. - (Topic 2)
You are developing an application by using C#. The application includes a method named SendMessage. The SendMessage() method requires a string input.
You need to replace "Hello" with "Goodbye" in the parameter that is passed to the SendMessage() method.
Which two code segments can you use to achieve this goal? (Each correct answer presents a complete solution. Choose two.)
A. Option A
B. Option B
C. Option C
D. Option D
Answer: B,C
Explanation: * The first parameter should be Hello.
* String.Replace Method (String, String)
Returns a new string in which all occurrences of a specified string in the current instance are replaced with another specified string.
This method does not modify the value of the current instance. Instead, it returns a new string in which all occurrences of oldValue are replaced by newValue.
Q106. - (Topic 2)
You are creating a class library that will be used in a web application.
You need to ensure that the class library assembly is strongly named.
What should you do?
A. Use the gacutil.exe command-line tool.
B. Use the xsd.exe command-line tool.
C. Use the aspnet_regiis.exe command-line tool.
D. Use assembly attributes.
Answer: D
Explanation: The Windows Software Development Kit (SDK) provides several ways to sign an assembly with a strong name:
* Using the Assembly Linker (Al.exe) provided by the Windows SDK.
* Using assembly attributes to insert the strong name information in your code. You can use either the AssemblyKeyFileAttribute or the AssemblyKeyNameAttribute, depending on where the key file to be used is located.
* Using compiler options such /keyfile or /delaysign in C# and Visual Basic, or the
/KEYFILE or /DELAYSIGN linker option in C++. (For information on delay signing, see
Delay Signing an Assembly.)
Note:
* A strong name consists of the assembly's identity—its simple text name, version number, and culture information (if provided)—plus a public key and a digital signature. It is generated from an assembly file (the file that contains the assembly manifest, which in turn contains the names and hashes of all the files that make up the assembly), using the corresponding private key. Microsoft. Visual Studio. .NET and other development tools provided in the .NET Framework SDK can assign strong names to an assembly.
Assemblies with the same strong name are expected to be identical.
Q107. - (Topic 2)
You are creating an application that reads from a database.
You need to use different databases during the development phase and the testing phase by using conditional compilation techniques.
What should you do?
A. Configure the Define TRACE constant setting in Microsoft Visual Studio.
B. Decorate the code by using the [DebuggerDisplay("Mydebug")] attribute.
C. Configure the Define DEBUG constant setting in Microsoft Visual Studio.
D. Disable the strong-name bypass feature of Microsoft .NET Framework in the registry.
Answer: C
Explanation: Use one debug version to connect to the development database, and a standard version to connect to the live database.
Q108. - (Topic 2)
