In Visual Basic, which of the following method converts a string to a number?
A. Convert
B. Tryparse
C. Extern
D. Parse
Answer: Option B
Solution(By Examveda Team)
InVisual Basic
, the TryParse
method is used to convert a string to a number while handling potential errors that might occur during the conversion. This method is commonly used when you want to attempt the conversion without causing an exception if the conversion fails.
The
TryParse
method is used as follows:
Dim strNumber As String = "123"
Dim intValue As Integer
If Integer.TryParse(strNumber, intValue) Then
' Conversion successful, intValue now holds the parsed value
Else
' Conversion failed, handle the error
End If
Option A,
Convert
, is a general-purpose class that provides various methods for converting between data types. While it can be used for converting strings to numbers, it's not the primary method used when error handling is a concern.
Option C,
Extern
, is not a method for converting strings to numbers in Visual Basic
.
Option D,
Parse
, is a method for converting strings to numbers, but it does not handle errors in the same way as TryParse
.
Therefore, the correct option is Option B: TryParse.
