Use StringBuilder

• Jun 26, 2019

Replaces string concatenation operations with method calls on a local StringBuilder instance, to improve performance (working with a StringBuilder is faster than concatenating strings).

Availability

Available from the context menu or via shortcuts:

• when the selection contains several assignment statements that are used to construct a string (each statement appends a string to the previously accumulated value).

Example

C#

│string result = s1;
result += s2;
result += s3;

VB.NET

│Dim result As String = s1
result += s2
result += s3

Result:

C#

StringBuilder resultBuilder = new StringBuilder(s1);
resultBuilder.Append(s2);
resultBuilder.Append(s3);

VB.NET

Dim lResultBuilder As StringBuilder = New StringBuilder(s1)
lResultBuilder.Append(s2)
lResultBuilder.Append(s3)
