自己来实现一下。
Codepublic static List<string> Splite(string src,char patChar)
{
List<string> result &＃61; new List<string>();
if (string.IsNullOrEmpty(src))
{
return null;
}
else
{
int endIndex &＃61; 0;
int frontIndex &＃61; -1;
while (endIndex<src.Length)
{
if (src[endIndex] !&＃61; patChar)
{
}
else
{
string temp &＃61; string.Empty;
if (endIndex - frontIndex - 1 > 0)
{
temp &＃61; src.Substring(frontIndex &＃43; 1, endIndex - frontIndex-1);
}
result.Add(temp);
frontIndex &＃61; endIndex;
}
endIndex&＃43;&＃43;;
}
if (frontIndex <&＃61;src.Length-1)
{
string temp&＃61;string.Empty;
if (frontIndex &＃43; 1 <&＃61; src.Length - 1)
{
temp &＃61; src.Substring(frontIndex &＃43; 1);
}
result.Add(temp);
}
return result;
}
}
public static string[] SpliteArray(string src, char patChar)
{
List<string> re&＃61; Splite(src,patChar);
if (re !&＃61; null)
{
return re.ToArray();
}
else
{
return null;
}
}
单元测试如下:
Code///
///Splite 的测试
///
[TestMethod()]
public void SpliteTest()
{
string[] srcList &＃61;
{
"i love this game",
" i love this game",
" i love this game",
"i love this game ",
"i love this game ",
"i love this game",
"i love this game ",
" i love this game ",
" i love this game ",
"i love this game",
" i love this game ",
};
foreach (string src in srcList)
{
string[] expected &＃61; src.Split(&＃39; &＃39;);
string[] actual;
actual &＃61; StringMagic.SpliteArray(src, &＃39; &＃39;);
bool equal &＃61; true;
for (int i &＃61; 0; i < expected.Length; i&＃43;&＃43;)
{
if (expected[i] !&＃61; actual[i])
{
equal &＃61; false;
break;
}
}
Assert.AreEqual(equal, true);
}
}
