ASP.NET: String Concatenation
From Wiki
Summary: An example of how strings can be concatenated with the StringBuilder class
If you concatenate a string like this:
- Dim s As String = ""
- s &= "This "
- s &= "is "
- s &= "an "
- s &= "example "
- Label1.Text = s
then you actually end up with 5 strings in memory rather than just the original one that you created. This obviously isn't very efficient.
Instead, you can use the System.Text.StringBuilder class which is both quicker and uses less memory as only one object is created:
- Dim sb As New StringBuilder
- sb.Append("This ")
- sb.Append("is ")
- sb.Append("an ")
- sb.Append("example")
- Label1.Text = sb.ToString()
