Example Analysis of StringBuilder usage in. NET and stringbuilder usage This example describes the usage of StringBuilder in. NET. Share it with you for your reference. The specific analysis is as follows: Why use StringBuilder? Why do we need to start with the features of the string object when using StringBuilder.When a string object is concatenated, a copy of the string object is copied for operation each time because of its immutability, and its own string remains in the memory, A large n

S1 = =

search splice pictures, there will be a lot of movie-related pictures (Chinese man-beast hybrid English named splice):The story is that two scientists, contrary to scientific ethics, use the human gene and the beast gene, do the hybridization experiment, to produce a new species, this species is a hybrid (splice), this hybridization is the mosaic of genetic sequences, resulting in the result of hybridization, resulting in the individual, animal not beast objects.It can be imagined that the gene

the close relationship between DNA methylation and human development and tumor disease,DNA methylation (DNA methylation), a form of chemical modification of DNA, can alter the genetic phenotype without altering the DNA sequence. DNA methylation plays an important role in maintaining normal cell function, transmitting genomic imprinting, embryo development and tumor occurrence, and has become a hotspot of epigenetics and epigenetics.How is the genome assembled? In general, the Assembly strategy

extremely inconvenient (the program can only find the rules of the field, split and then take out, in splicing, in the preservation), to maintain trouble3: It is convenient to change rules by group, but it is more troublesome if I want to follow rules to see if it belongs to those groups, or to authorize certain groups according to the rules. If you use an association table, it's not a problem, it's also good for program maintenance. Above

will also cause garbage collection frequent execution, affecting performance. So string concatenation is suitable for a small number of splicing, for a large number of splicing, it is recommended to use StringBuilder.The following is a simple process of string concatenation and StringBuilder stitching.string concatenation process: String a= ' a '; A+=b;1. Open enough temporary storage space to secure enoug

, Because the following operation code changes the current parameter [I] value, and we need to change it back at last, we need to assign a value. At last, we need to input Parameter [I] = parameterData; This can be done in turn. Parameter [I] = parameter [I]. split ("=") [0] + "=" + parameter [I]. split ("=") [1] + onlyString; To redefine the current parameter, parameter [I]. split ("=") [0] is the string of the obtained parameter, as follows: Parameter [I]. split ("=") [1] is used to obta

Maybe some of the above titles are well known, and all those who have learned PHP know that the subscript of the array in PHP allows us to customize it. The array in PHP is exactly a key-value pair. In oC, we need to use a dictionary for storage. Of course, Java uses map to store key-value pairs. The following is a very practical example. network requests have get and post methods, which have their own advantages. When the form is submitted, the POST method uses more, and the get method is used

image quality. In my opinion, the "standard" status is already good. If the image quality is high, the compression time is long.It is best to save the settings so that you do not need to change it the next time you open it. Click "save" and enter your custom Template Name. 4. Start compression:Click Start To Start compression. The original time is the current video position. During compression, you can use the sum of "used time" + "remaining time" to estimate the total time required. The number
