I m a beginner, can you give an example of the specific usage of split and replace in C?

string a = "a,b,c";

string arr = ',');Based on the comma, it is divided into an array of strings, and the contents of the array are three values: a, b, and c.

string s = ',', ';');This is a semicolon instead of a comma, and the result is: a; b;c

split is to separate strings into arrays.

For example, string str="kk;dd;ff;gg;hh";

string ss=';');

replace is to replace some characters in a string with new characters.

string str="kk;dd;ff;gg;hh";

string ss=";","-");

Then the replaced string is kk-dd-ff-gg-hh, which is the most commonly used usage, split and replace are different from one parameter is char and the other is string

Hope mine is helpful to you.

It's all string methods.

replace the specified character (string) match in the string with other characters (string);

split divides the string into an array of strings according to the specified delimiter;

If there is a path string:

filenm = "c://temp";

Use replace:

abc", "edf");

filename becomes"c://temp";

Use split:

string delimstr = "\\";

char delimiter = ;

string strs = ;

string str2 = strs[ -1];

The resulting array strs str2=

split, which splits the string into an array according to the specified symbol format, and returns an array.

replace, which replaces the specified characters in the string with the specified content, and returns the string.

What are you talking about?

The main usage is to split the input string according to the characters in the specified set, and return the divided string array.

In fact, there are two main implementations.

char chars)

Multiple splits for characters.

string strings,stringemptyoption option)

Multiple splits for strings. The second parameter refers to whether or not to return an empty split.

Such as:"abcdabc".split('b') results in a new string

abcdabc".split(‘b’,'c'The result is a new string

abcdabc".split(new string,"Empty strings are not returned"The result is a new string

abcdabc".split(new string,"Returns an empty string"The result is a new string

Use. The net reflector decompiler looks at the overload of the method.

After understanding, write a demo test to deeply understand the specific usage of split.

It's just the idea of splitting into arrays.

c) Returns a substring of strings containing the character c.

The landlord wants to remove the enter and " " in the text and get the data in the text.

is the text that is read in.

2. string readtext = "", "@").split('@');

This will make the data into the readtext array, so you can work with the array.

Floors 1 and 2 are right, such as:

string strtest1 = "";

string strtest2 = "";

string strre = string ","To split the characters");

strtest1 = strre[0].trim().tostring();

strtest2 = strre[1].trim().tostring();

string test=“123a|1231”.replace("|","");

1.From the regex match to item 5, take the grouped value named txt and include it"

Replace with"|"。

2.Replace the value of str with'|'Split into a string array (a collection of multiple strings) and get the first string.

split converts strings into arrays.

split is a split, you want to remove, you should use the replace method.

string str="a|b|c|d"

|0].tostring())

string strarray = '|

response,write(strarray[0]);

That's OK, maybe the difference in quotation marks.

public static string composemessage(string source, string...replacement) "1;

string pattern = , end);

source = , replacement[i]);

return source;

public static void main(string args) Hello! The amount of this purchase is in your account.

The balance on is $"。

replace.

public class q272956869

public static void main(string args)

string temp = Dear customer $Hello! The amount of this purchase is $, and the balance on your account $ is $. "

string msg = composemessage(temp, "Sister Feng", 8090", yy-009", 678");

public static string composemessage(string template, string name, string amount,string account,string balance)

template="$name);

template="$amount);

template="$account);

template="$balance);

return template;
