Simple Method and example of a string

Split Splits a string into a group of arrays to traverse the Array
Example: string s1 = "abc, 123, lcf, I am Chinese ";
String [] items = s1.Split (',');
Foreach (string item in items)
{
Console. Write (item + "");
}
The above code will be output: abc 123 lcf I am a Chinese
 
Substring is used to intercept a string. The value of this parameter indicates to intercept the returned string from this parameter.
Example: string s1 = "February 1234 ";
S1 = s1.Substring (2 );
Console. WriteLine (s1 );
The above code will be output :,
 
 
IndexOf is used to obtain the position of this parameter value in this string, and a value is returned.
Example: string s1 = "February 1234 ";
Int i1 = s1.IndexOf ("4 ");
Console. WriteLine (i1 );
The above code will be output: 3
 
Contains: returns a Boolean value if the string Contains this parameter value.
Example: string s1 = "February 1234 ";
Bool i1 = s1.Contains ("2 ");
Console. WriteLine (i1 );
The above code will output: True
 
The CompareTo parameter value is compared with the string. If the value is identical, 0 is returned, and 1 is returned.
Example 1: string s1 = "February 5, 8 ";
Int i1 = s1.CompareTo ("August 8 ");
Console. WriteLine (i1 );
Example 2: Console. WriteLine ("Enter Password :");
String s1 = Console. ReadLine ();
Console. WriteLine ("Confirm Password :");
String s2 = Console. ReadLine ();;
Int i1 = s2.CompareTo (s1 );
While (true)
{
If (i1 = 0)
{
Console. WriteLine ("the two inputs are consistent! ");
Return;
}
Else
{
Console. WriteLine ("no two inputs! Enter ") again ");
S1 = Console. ReadLine ();
Console. WriteLine ("Enter again :");
S2 = Console. ReadLine ();
I1 = s2.CompareTo (s1 );
}
}
 
 
If the Equals parameter is the same as the string, True is returned, and False is returned if the Equals parameter is different.
Example: string s1 = "People's Republic of China ";
String s2 = "Republic of China ";
Bool B = s1.Equals (s2 );
Console. WriteLine (B );
The above code returns: False
 
 
Insert a character into the string. The parameter value must be the start position, and then enter the inserted content.
Example: string s1 = "People's Republic of China ";
S1 = s1.Insert (0, "medium ");
Console. WriteLine (s1 );
Return the code above: People's Republic of China
 
 
 
Remove the character after the specified position
Example: string s1 = "People's Republic of China ";
S1 = s1.Remove (3 );
Console. WriteLine (s1)
Return the code above: Republic of China
 
 
 
Replace
Example: string s1 = "People's Republic of China ";
S1 = s1.Replace (" ","");
Console. WriteLine (s1 );
Return the code above: People's Republic of China
 
 
StartsWith (EndsWith) determines whether the pre-(post) part of the string matches the Parameter
For example, string s1 = http://www.bkjia.com;
Bool B = s1.StartsWith ("http ://");
Bool c = s1.EndsWith (". com ");
Console. WriteLine (B );
Console. WriteLine (c );
The preceding Code returns True False.
 
 
Trim (TrimStart) (TrimEnd) clears the spaces (characters) at the beginning and end of the string)
Example: string s1 = "http://www.bkjia.com ";
String s2 = s1.Trim ();
String s3 = s1.TrimStart (new char [] {'h', 't', 'w '});
String s4 = s1.TrimEnd (new char [] {'', 'M '});
Console. WriteLine (s2 + "separated ");
Console. WriteLine (s3 );
Console. WriteLine (s4 );
The above code returns separately: http://www.bkjia.com separated
