字符串: #EXTM3U#EXTINF:230,http://192.168.167.20/mp3/2.女歌手/R-容祖儿/容祖儿-Give Love A Break/身骄肉贵(电影身骄肉贵主题
曲).mp3http://192.168.167.20/mp3/2.女歌手/R-容祖儿/容祖儿-Give_Love_A_Break/身骄肉贵(电影身骄肉贵主题曲).mp3

我想将 以 "http" 开头,以".mp3"结尾,这样分割字符串,如何实现?

Ben,你好:
你可以使用string的折分(splict)功能把字符分成一個字符數組即可

String.Substring Method [C#]

Retrieves a substring from this instance.

Overload List
Retrieves a substring from this instance. The substring starts at a =
specified character position.


[C#] public string Substring(int);
Retrieves a substring from this instance. The substring starts at a =
specified character position and has a specified length.


[C#] public string Substring(int, int);

Example
[Visual Basic]=20
Dim myString As String =3D "abc"
Dim test1 As Boolean =3D String.Compare(myString.Substring(2, 1), "c") =
=3D 0 ' This is true.
myString.Substring(3, 1) ' This throws ArgumentOutOfRangeException.
Dim test2 As Boolean =3D String.Compare(myString.Substring(3, 0), =
String.Empty) =3D 0 ' This is true.
[C#]=20
String myString =3D "abc";
bool test1 =3D String.Compare(myString.Substring(2, 1), "c") =3D=3D 0; =
// This is true.
myString.Substring(3, 1); // This throws ArgumentOutOfRangeException.
bool test2 =3D String.Compare(myString.Substring(3, 0), String.Empty) =
=3D=3D 0; // This is true.

使用splict将其才分后存储到数组就可以了
