VB.Net + and & Operator
The + and & operators in VB.NET can both be used to join strings. However, there is a key difference between the two operators:
The & operator is specifically designed for joining strings. It is more efficient than the + operator for joining strings, and it is also less likely to produce unexpected results.
The + operator is a general-purpose operator that can be used to add numbers, strings, and other types of data. It is not as efficient as the & operator for joining strings, and it is more likely to produce unexpected results if one of the operands is not a string.
- Use + when you are certain that both operands are non-null and you want to perform simple string concatenation.
- Use &when dealing with potentially null strings or when you want more robust string concatenation that handles null or empty values.
In most cases, using & is preferred in VB.NET because it provides more predictable and safe string concatenation behavior, especially when working with strings that may have null values.
