What does string builder do???

Question

what string builder command do in the asp.net cs file.

Answer 1

It is not a command - it is a class which is part of the Base Class Library, in the System.Text namespace.

The StringBuilder class lets you construct large strings in an efficient manner.

There is a Microsoft artical titled "Using the StringBuilder Class" that explains how to use this class.

Answer 2

It's a way to build strings that doesn't create lots of intermediate strings (that then need to be cleaned up by th GC).

Example code (don't do this):

string s = "";
for (int i=0; i<10000; i++)
   s += "test";

Every time you add something to a string, you create a new string. The old version is discarded and needs to be collected by the GarbageCollector.

Stringbuilder version:

StringBuilder sb = new StringBuilder();
for (int i=0; i<10000; i++)
{   sb.Append("test"); }
string s = sb.ToString();
