Explanation Explanation: await sourceStream.WriteAsync(encodedText, 0, encodedText.Length); The following example has the statement await sourceStream.WriteAsync(encodedText, 0, encodedText.Length);, which is a contraction of the following two statements: Task theTask = sourceStream.WriteAsync(encodedText, 0, encodedText.Length); await theTask; Example: The following example writes text to a file. At each await statement, the method immediately exits. When the file I/O is complete, the method resumes at the statement that follows the await statement. Note that the async modifier is in the definition of methods that use the await statement. public async void ProcessWrite() { string filePath = @"temp2.txt"; string text = "Hello World\r\n"; await WriteTextAsync(filePath, text); } private async Task WriteTextAsync(string filePath, string text) { byte[] encodedText = Encoding.Unicode.GetBytes(text); using (FileStream sourceStream = new FileStream(filePath, FileMode.Append, FileAccess.Write, FileShare.None, bufferSize: 4096, useAsync: true)) { await sourceStream.WriteAsync(encodedText, 0, encodedText.Length); }; } Reference: Using Async for File Access (C# and Visual Basic) https://msdn.microsoft.com/en-us/library/jj155757.aspx
| Question ID 17073 | You are evaluating a method that calculates loan interest. The application includes the
following code segment. (Line numbers are included for reference only.)
When the loanTerm value is 5 and the loanAmount value is 4500, the loanRate must be set
to 6.5 percent.
You need to adjust the loanRate value to meet the requirements.
What should you do?
|
| Option A | Replace line 15 with the following code segment: loanRate = 0.065m;
|
| Option B | Replace line 07 with the following code segment: loanRate = 0.065m;
|
| Option C | Replace line 17 with the following code segment: interestAmount = loanAmount * 0.065m * loanTerm;
|
| Option D | Replace line 04 with the following code segment: decimal loanRate = 0.065m;
