Why to use StringBuilder

Why use StringBuilder to start with the properties of a string object.

string object when string stitching, Because of the immutability of the string, the string object will be duplicated every time, copying a copy out of the operation, and its own strings remain in memory, a large number of temporary fragments will cause negligible performance loss. Therefore, it is recommended to use StringBuilder

the simple way to use StringBuilder

string S1 = "33";

String s2 = "44";

String s3 = "55"; The demand is to S1 S2 S3 together. This is a typical string concatenation.

With StringBuilder, no useless temporary strings are generated.

StringBuilder SB =new StringBuilder ();

Stitching method One

Sb. Append (S1);

Sb. Append (S2);

Sb. Append (S3);

//splicing mode two  

Because the Append () method returns a This, which is the object itself. So you can use this method.

Chained programming jquery is commonly used in this way

Sb. Append (S1). Append (S2). Append (S3);

Finally put SB. ToString () Just a little bit better.

The Ps:appendline () method can automatically add a carriage return.
