1, separated by the string:
using System.Text.RegularExpressions; string str="aaajsbbbjsccc"; string[] sArray=Regex.Split(str,"js",RegexOptions.IgnoreCase); foreach (string i in sArray) Response.Write(i.ToString() + "<br>");
Output: aaa bbb ccc
2, separated by a plurality of characters:
string str="aaajbbbscccjdddseee";
string[] sArray=str.Split(new char[2]{'j','s'});
foreach(string i in sArray) Response.Write(i.ToString() + "<br>");
Output Results: AAA BBB CCC ddd Eee . 3, a single character to separate:
string str="aaajbbbjccc";
string[] sArray=str.Split('j');
foreach(string i in sArray) Response.Write(i.ToString() + "<br>")
Output: aaa bbb
ccc
When creating an instance of the Regex class, overloaded constructor there is a requirement to pass a enumeration value RegexOptions, I believe this will be very useful to enumerate it will not seek passed in the constructor. Today, we take a look at the role of the enumeration.
We simply look to knock out the code:
None = 0, // do not specify setup options. IgnoreCase = 1, // the specified insensitive matching. Multiline = 2, // multiline mode. Change the meaning of ^ and $ so they match at each end of the line beginning of the line and any line, not just at the beginning and end of the match the entire string. ExplicitCapture = 4, // specify a valid capture only the form (? <Name> ...) groups explicitly named or numbered. This allows unnamed parentheses to act as a non-capturing group, and not the expression syntax (:? ...) is clumsy. Compiled = 8, // specified regular expression compiled into an assembly. This results in faster execution but increases startup time. When calling System.Text.RegularExpressions.Regex.CompileToAssembly (System.Text.RegularExpressions.RegexCompilationInfo [], System.Reflection.AssemblyName) method, this value should be assigned to the attribute. Singleline = 16, // specified single-line mode. Change the point (.) Meaning that it (and not match with each character except \ n's) match with each character. IgnorePatternWhitespace = 32 // elimination mode and enable non-blank escaped marked by # of comments. However, System.Text.RegularExpressions.RegexOptions.IgnorePatternWhitespace value does not affect or eliminate white space character class. RightToLeft = 64 // specify the search from right to left instead of left to right. ECMAScript = 256, // enable ECMAScript-compliant behavior for the expression. This value can only use the System.Text.RegularExpressions.RegexOptions.IgnoreCase System.Text.RegularExpressions.RegexOptions.Multiline and System.Text.RegularExpressions.RegexOptions.Compiled values together. This value is used in conjunction with any other values are will result in an exception. CultureInvariant = 512 // Specify ignore regional differences in language.
