开发笔记1:C#如何将两个字符串去掉重复部分
字符串str1="45500A123F00000125000X", 字符串str2="45500A123F00100025000X"。两个字符串代表的是一个条码范围,绿色部分代表的是条码的流水(1~1000)。在不清楚流水截取规则,可以通过下面算法自动去重,获取到条码流水。
代码如下:
#region 去掉两者相同的部分
public static void RemoveLike(string str1, string str2, ref string str1Result, ref string str2Result)
{
//从左往右去重
for (int index = 0; index < str1.Length; index++) //从左往右逐位截取
{
if (index == (str1.Length - 1)) //无重复的情况下,进行截取
{
str1Result = str1.Substring(index, str1.Length - index);
str2Result = str2.Substring(index, str2.Length - index);
break;
}
else if (str1.Substring(index, 1) == str2.Substring(index, 1)) //重复自动跳过
{
continue;
}
else //存在重复情况下,从左截取
{
str1Result = str1.Substring(index, str1.Length - index);
str2Result = str2.Substring(index, str2.Length - index);
break;
}
}
//再从右往左去重
for (int index = str1Result.Length - 1; index > 0; index--)
{
if (index == 0) //无重复的情况下,进行截取
{
str1Result = str1Result.Substring(0, 1);
str2Result = str2Result.Substring(0, 1);
break;
}
else if (str1Result.Substring(index, 1) == str2Result.Substring(index, 1))//重复自动跳过
{
continue;
}
else//存在重复情况下,从左截取
{
str1Result = str1Result.Substring(0, index + 1);
str2Result = str2Result.Substring(0, index + 1);
break;
}
}
}
#endregion
调用:
string str1 = "45500A123F00000125000X";
string str2 = "45500A123F00100025000X";
string result1 = "";
string result2 = "";
RemoveLike(str1, str2, ref result1, ref result2);
结果:
原字符串1:45500A123F00000125000X
原字符串2:45500A123F00100025000X
去重后字符串1=0001
去重后字符串2=1000
