Question

我试图在一个文本块之间提取一个文本块而没有这样做。

文本块看起来像这样

!###################################################################################################
!# Approved : YES
!# REASON: sample reason
!# DEVICE: device1
!# ACL: Acl_sample

access-list <Rule No> extended permMuramat esp <IPaddress> <subnet mask> <IPaddress> <subnet mask> eq <Port Number>
access-list <Rule No> extended permMuramat udp <IPaddress> <subnet mask> <IPaddress> <subnet mask> eq <Port Number>

!##########################################################################
!# REASON:test
!# DEVICE: RTP
!# SECTION : Foundational

access-list <Rule No> permMuramat tcp <IPaddress> <subnet mask> <IPaddress> <subnet mask> eq <Port Number>
!######################################################################################################
!# APPROVED : YES
!# REASON: test1xxx
!# DEVICE: xxx test1 Devices
!# SECTION: test1
!# REQUESTER: test1@test1test2.com
!# Exp. Date : 8/2016

   access-list <Rule No> permMuramat tcp <IPaddress> <subnet mask> <IPaddress> <subnet mask> eq <Port Number>
access-list <Rule No> permMuramat <IPaddress> <subnet mask> <IPaddress> <subnet mask> eq <Port Number>

基本上将所有内容都放入数组列表中。

我试图遵循一种模式，即起始索引将以＆＃34;！＃＆＃34;开头。而下一个角色不是＆＃34;＃＆＃34;然后这就成了＆＃34; Startindex＆＃34;如果下一个字符以＆＃34;！＆＃34;开头，那么结束索引将是并且进行中的角色至少有两个＆＃34;＃＆＃34; es。

尽管失败但是:(

该文件基本上是一个rtf文件。这就是我的代码现在所看到的。

string path = @"\\WDMYCLOUD\Public\data.rtf";

            string rtfText = File.ReadAllText(path);

            RichTextBox rtBox = new RichTextBox { Rtf = rtfText };

            var plainText = rtBox.Text;

            var charArr = plainText.ToCharArray();

            var arrBuffer = new ArrayList();

            string tmp = "";

            for (int i = 0; i < charArr.Length; i++)
            {
                int bufferIndex;

                var startIndex = bufferIndex = i;

                if (charArr[startIndex] == '!' && charArr[startIndex + 1] == '#' &&
                    charArr[startIndex + 2] != '#' && charArr[startIndex + 2] != ' ')
                {
                    for (int j = bufferIndex; j < charArr.Length; j++)
                    {
                        if (charArr[j] == '!' && charArr[j + 1] == '#' && charArr[j + 2] == '#')
                        {
                            bufferIndex = j + 2;

                            for (int charStartIndex = startIndex; charStartIndex <= bufferIndex; charStartIndex++)
                            {
                                tmp = tmp + charArr[charStartIndex];
                            }
                            arrBuffer.Add(tmp);
                            tmp = "";
                        }
                        arrBuffer.Add(tmp);
                        tmp = "";
                    }

                }
            }

我在数组列表中得到了各种各样的混乱，而我希望它包含块。

预期输出应为

  First Block:

    !# Approved : YES
    !# REASON: sample reason
    !# DEVICE: device1
    !# ACL: Acl_sample

    access-list <Rule No> extended permMuramat esp <IPaddress> <subnet mask> <IPaddress> <subnet mask> eq <Port Number>
    access-list <Rule No> extended permMuramat udp <IPaddress> <subnet mask> <IPaddress> <subnet mask> eq <Port Number>

    Second Block:

   !# REASON:test
    !# DEVICE: RTP
    !# SECTION : Foundational

    access-list <Rule No> permMuramat tcp <IPaddress> <subnet mask> <IPaddress> <subnet mask> eq <Port Number>

    Third block:

      !# APPROVED : YES
    !# REASON: test1xxx
    !# DEVICE: xxx test1 Devices
    !# SECTION: test1
    !# REQUESTER: test1@test1test2.com
    !# Exp. Date : 8/2016

       access-list <Rule No> permMuramat tcp <IPaddress> <subnet mask> <IPaddress> <subnet mask> eq <Port Number>
    access-list <Rule No> permMuramat <IPaddress> <subnet mask> <IPaddress> <subnet mask> eq <Port Number>

有人可以帮我吗？

Answer 1

也许你可以尝试另一种方法：

string rtfText = File.ReadAllText(path);
List<string> loStringList = new List<string>();
StringBuilder loBuilder = null;

foreach (var lsLine in Regex.Split(rtfText, Environment.NewLine))
{
    if (lsLine.StartsWith("!##"))
    {
        if (loBuilder != null)
            loStringList.Add(loBuilder.ToString());
        loBuilder = new StringBuilder();
    }
    else if (loBuilder != null)
        loBuilder.AppendLine(lsLine);
}

if (loBuilder != null)
    loStringList.Add(loBuilder.ToString());

Answer 2

我做了类似的事情，我做的是检查每一行是否包含某个字符，在你的情况下＆＃34; ##＆＃34;，如果它不包含它，将它添加到你的字符串/列表。

string[] lines = System.IO.File.ReadAllLines(@"[..]file.extension");
foreach (string line in lines)
  if (!line.Contains("##")
  {
     //..
  }

希望这有所帮助。
