我想提取 ProposerName

【问题讨论】：

让我明白，您可以成功地将 pdf 转换为文本，现在您要提取数据吗？好吧，这取决于您的最终文本文件的外观。您可以使用正则表达式模式，或者如果它具有 .csv 格式或其他格式，您可以将文本拆分为行（通过“\n”），然后按列拆分每一行。视情况而定。
如果你还没有做，你可以使用pdftotext将它转换成文本xpdfreader.com/pdftotext-man.html然后你提取数据。
我已经更新了问题描述。这是一种选择 ProposerName 及其值的方法。
我昨天已经回答了：D 刚刚修复了regexPattern 字符串中的一些细节。试试看！

【解决方案1】：

看看这段字符串： Proposerdetails1.ProposerName:RAJINDERKUMARGUPTA2.ProposerAddress:NEARPIPALCHOWK

你看到<Key>:<Value>. 中的ProposerName:RAJINDERKUMARGUPTA2. 模式了吗？

你想要的是从文本中找到这个特定的键/值对并取值。

您可以使用Regular Expressions (Regex)。

//Imagine that your data is stored here in 'fullText'
public static string GetProposerName(string fullText)
{

   /* Here's the regex filter for us to find a piece of string in the data with the 
    * key ProposerName, some value that we don't know yet and a . termnation.
    * Now take a look in the content inside the (). 
    * This is a group. The symbols between it means that we
    * want to get everything, any content, that is there inside the group. */
   string regexPattern = "ProposerName:(.*?)\\.";

   //Use this classes from System.Text.RegularExpressions
   Match match = Regex.Match(fullText, regexPattern);

   //Important test, it may not find anything...
   if (!match.Success) return null;

   /* If your code reaches here means that you've find the pattern inside the text.
    * Now you take only the value inside the group as a string and voila!*/
   string proposerName = match.Groups[0].Value;

   return proposerName;
}
