Building strings in memory using the string concatenation operator, the plus sign (+) in C#, causes a few problems. The string class is immutable which means that once a string is created in memory, the size and location of this string value cannot grow or shrink. Thus, when you use the concatenation operator you are creating a new string in a new location in memory and telling the .NET garbage collector to throw away the old string value. This causes the garbage collector to perform extra work and slows down your application. This is where using the StringBuilder class can help you out. In this blog post you learn the basics of using the StringBuilder class.)
