ref image

From this field, the ref indicates the reference. out is the output.Public void getrefstr (Ref String Str) {STR = "Hello, you have changed to ref "}Public void getoutstr (Out String outstr) {outstr = "Hello, you are the output value of out ";}

Principles of program executionIt doesn't seem easy to get a sense of the bunch of concepts and their relationships, because most C # programmers don't know about the managed heap (the "heap") and the line stacks ("stack"), or know them, but don't

Preface I have been training at the company for the past few days, and I have some basic knowledge. At the same time, I also took this opportunity to consolidate my own infrastructure. The foundation is too important. I have been looking at

Fundamentals of MATLAB image processing2.2.1 Image File format and image type1. Several image file formats supported by MATLAB:⑴jpeg (Joint photogyaphic Expeyts Group): An image compression format called the joint Image Expert group.⑵bmp (Windows

1. Several image file formats supported by MATLAB:⑴jpeg (Joint photogyaphic Expeyts Group): An image compression format called the joint Image Expert group.⑵bmp (Windows Bitmap): There are 1-bit, 4-bit, 8-bit, 24-bit uncompressed images, and 8-bit

  If you use the STL algorithm frequently, you will notice that the function object is passed in the form of passing values as follows: sort, for_each, _ Compare _ comp instead of _ Compare & _ comp. template inline void

There has been a lot of explanation about the usage and the difference between ref and out, and it's just an explanation that's easier to understand than to write about me.Both ref and out can be used to return data in a function, similar to

In the current project development process, the customer needs to generate Word documents based on the database data, and found two solutions during the communication with colleagues. 1. use the Program to generate an HTML page of the report

1. First pass Program Generate the HTML page of the report style, and modify the HTML page suffix to Doc. 2. Customize the template file of the Word document, operate the Word template in C #, and generate a new word document. The first scheme is
