Reads Binary file and encodes it to Base64 string using C#.NET

public static string BinaryToBase64String(string filePath)
FileStream fileStream = new FileStream(filePath, FileMode.Open, FileAccess.Read); // Creates new file stream for binary file with read access
BinaryReader binaryReader = new BinaryReader(fileStream); // Creates the binary reader with file as input
byte[] binaryByteArray = binaryReader.ReadBytes((int)fileStream.Length); // Reads the bytes from binay file and stores into byte array
return Convert.ToBase64String(binaryByteArray); // Encodes the byte array to Base64 string and returns the string
catch (Exception ex)
return ex.Message; // Returns the exception message

Locate the element inside table row based on text inside row's cell

This is one of the powerfull XPATH query I have seen

selenium.Check("//tr[.//p[contains(text(),'AT Test User 1')]]//input[contains(@name,'members_new')]");

here //tr[.//p[contains(text(),'AT Test User 1')]] returns the table row which has p tag containing text AT Test User 1. Notice the . used here, which refers to the context node
And once that row is selected //input[contains(@name,'members_new')] locates the input element contained in that row.
