常见的很多都是截取一个字符串中的一组，其实很多时候我们需要用到截取整个字符串中，所有匹配到的字符串，那得到将是一个列表。
列如："{{localization:0-35}u}{localization:50-50},jdjsi{emoj,{localization:12-58}}"
截取中间的坐标，根据"{localization:"和 "}"进行匹配，得到结果如下打印

public class Test : MonoBehaviour
{
public string mContent = "{{localization:0-35}u}{localization:50-50},jdjsi{emoj,{localization:12-58}}";
public string mStartStr = "{localization:";
public string mEndStr = "}";
void Awake()
{
var list = GetAllSubstring(mContent, mStartStr, mEndStr);
for (int i = 0; i < list.Count; i++)
{
Debug.LogError(list[i]);
}
}
public List GetAllSubstring(string content, string startStr, string endStr)
{
List resultList = new List();
int len = content.Length;
int startLen = startStr.Length;
for (var i = 0; i < len; i++)
{
string a = startStr.Substring(0, 1);
if (content[i].ToString() == a)
{
int startIndex = (i + startLen - 1);
if (startIndex < len)
{
a = content.Substring(i, startLen);
if (a.Equals(startStr))
{
// 循环找出结尾匹配
for (int endIndex = startIndex; endIndex < len; endIndex++)
{
if (content[endIndex].ToString() == endStr)
{
// 得到长度
int splLen = endIndex - startIndex;
string result = content.Substring(startIndex + 1, splLen - 1);
resultList.Add(result);
break;
}
}
}
}
}
}
return resultList;
}
}
