C#字符串分割

C#中字符串分割
有时我们需将一个字符串用另一个字符串来分割成字符串字组。而C#中string.split只提供用char来分割。怎么办？
用的时候直接调用第一个函数。

 

/// <summary>

/// 将字符串分割成数组

/// </summary>

/// <param name="strSource"></param>

/// <param name="strSplit"></param>

/// <returns></returns>

public string[] StringSplit(string strSource,string strSplit)

{

string[] strtmp = new string[1];

int index = strSource.IndexOf(strSplit,0);

if(index<0)

{

strtmp[0] = strSource;

return strtmp;

}

else

{

strtmp[0] = strSource.Substring(0,index);

return StringSplit(strSource.Substring(index+strSplit.Length),strSplit,strtmp);

}

}

/// <summary>

/// 采用递归将字符串分割成数组

/// </summary>

/// <param name="strSource"></param>

/// <param name="strSplit"></param>

/// <param name="attachArray"></param>

/// <returns></returns>

private string[] StringSplit(string strSource,string strSplit,string[] attachArray)

{

string[] strtmp = new string[attachArray.Length+1];

attachArray.CopyTo(strtmp,0);



int index = strSource.IndexOf(strSplit,0);

if(index<0)

{

strtmp[attachArray.Length] = strSource;

return strtmp;

}

else

{

strtmp[attachArray.Length] = strSource.Substring(0,index);

return StringSplit(strSource.Substring(index+strSplit.Length),strSplit,strtmp);

}
