StringBuilder.Append Method (String)
Appends a copy of the specified string to this instance.
Assembly: mscorlib (in mscorlib.dll)
The StringBuilder object, as the following example illustrates.method modifies the existing instance of this class; it does not return a new class instance. Because of this, you can call a method or property on the existing reference and you do not have to assign the return value to a
bool flag = false; System.Text.StringBuilder sb = new System.Text.StringBuilder(); sb.Append("The value of the flag is ").Append(flag).Append("."); Console.WriteLine(sb.ToString()); // The example displays the following output: // The value of the flag is False.
If value is null, no changes are made.
The capacity of this instance is adjusted as needed.
Notes to Callers:
In the.NET Framework 4 and the .NET Framework 4.5, when you instantiate the StringBuilder object by calling the StringBuilder(Int32, Int32) constructor, both the length and the capacity of the StringBuilder instance can grow beyond the value of its MaxCapacity property. This can occur particularly when you call the and AppendFormat methods to append small strings.
