c Write the data in the array to text

The ** on the first floor contains several key steps. I guess that's enough, hehe.

int a=new int[10];Life Definition Space size int a=new int [5] Declare the space size and assign int a=new int to the above meaning string a=new string [10]; Life defines the size of the space.

string a=new string [5] declares the size of the space and assigns a value.

string a=new string is the same as the previous meaning.

There is no consolation to achieve your purpose

If you want to sort it, add one more sentence:

int array = ;;

The read data must be the datatable, the datarow of the looping datatable, and the write array one by one.

What is a line for a text file?

The so-called line is

r is the carriage return.

n is a line break.

streamwriter wr = new ..omitted); This method adds a line break at the end of the character being written.

So to call you should call the following method:

Calling the method will do the trick.

ArrayList is a list of objects, similar to the role of arrays, you add the string of each row to arrtext, to access the data in the arraylist you have to access the arrtext [number starting from 0], you are wrong to access that way. ','You can't use it that way.

string result=file path).split(',');

Quantity. As per your requirements.

string content = "c:\c#.txt");

string contentarray = char ,

Put the list. listlist = new list();

for (int i = 0;i < i+=3)}} list is what you need.

You can use the for loop statement + file operation function to read and store data in the file into an array.

1. The C standard library provides a series of file operation functions. File manipulation functions are usually named in the form of the word f+ (f is short for file), and their declarations are located in the header file. For example:

The fopen and fclose functions are used to open and close files; fscanf and fgets functions are used for file reading; The fprintf and fputs functions are used for file writing; The ftell and fseek functions are used to obtain and set the file operation location. The general C language course has a chapter on file manipulation, and you can find this textbook for further study.

2. Example: include

int i,a[100];

int main()

for(i=0;fscanf(fp1,"%d",a+i)!=eof;i++) continuously reads integers from the input file to array a

for(;i--;fscanf(fp2,"%d ",a[i]);Write array a in reverse order to the output file.

fclose(fp1);Close the input file.

fclose(fp2);Closing the output file is equivalent to saving return 0; }

string[,]arr = new string[15,15];A two-dimensional array to be written to a txt file.

string filename = "";

string sign = " ";Symbols separating elements between them, set to spaces here, you can change the settings yourself.

streamwriter sw = new streamwriter(filename, true);The first parameter is the name of the file that reads the stream, and the second parameter is whether the file can be created if the file does not exist, true is to create a new file, and false is not to create.

for (int i = 0; i < 15; i++)

To give you a paragraph to write txt.

if (}

static void txt(string src));This allows you to put each line into one item in the array: int idata = new int[;

for (int i = 0;i < i++) If each line is a number, this paragraph converts the string to an integer}
