How to VB.NET String.Contains()
The Contains method in the VB.NET String Class is a useful function that enables you to check whether a specified parameter string exists within another string. By invoking the Contains method, you can efficiently determine if a particular substring is present within a larger string, allowing you to perform conditional logic or extract relevant information based on the presence or absence of the target substring. This method provides a convenient and straightforward way to handle string manipulation and search operations in VB.NET.
- String str - input String for search
- Boolean - Yes/No.
The Contains method in the VB.NET String Class is designed to provide a Boolean value indicating whether a specified substring exists within a given string. If the substring is found within the string, the method returns true, signifying that the substring is present.
Conversely, if the substring is not found, the method returns false, indicating that the substring does not exist within the string. For example, when using the Contains method with the string "This is a Test", searching for the substring "is" will result in a true value, confirming its presence. However, when searching for the substring "yes", the method will return false, as the substring is not found in the original string. This functionality allows for efficient and convenient substring detection in VB.NET programming.
