C# 基于某些字符从文本框自动捕获值

我想要一个功能，用户可以在文本框中输入一些文本，并且基于一些预定义的字符，我必须识别用户可以链接到的不同属性。 例如：在文本框中，用户输入为： “您好@Sunil您将在#桌面上工作，其优先级为！1”

        string TitleText = "Hello @Sunil you are going to work on #Desktop which has a priority of !1 ";
        string title;
        string devname;
        string devteam;

        title = TitleText.Substring(TitleText.IndexOf("#")+1);
        title = title.Substring(0,title.IndexOf(" "));

        devname = TitleText.Substring(TitleText.IndexOf("@") + 1);
        devname = devname.Substring(0, devname.IndexOf(" "));

        devteam = TitleText.Substring(TitleText.IndexOf("!") + 1);
        devteam = devteam.Substring(0, devteam.IndexOf(" "));

现在从这些数据中，我想提取开发者的名字，也就是说，基于@..，也就是sunil。 团队名称基于#char，即桌面..和任务优先级，基于！char是1

        string TitleText = "Hello @Sunil you are going to work on #Desktop which has a priority of !1 ";
        string title;
        string devname;
        string devteam;

        title = TitleText.Substring(TitleText.IndexOf("#")+1);
        title = title.Substring(0,title.IndexOf(" "));

        devname = TitleText.Substring(TitleText.IndexOf("@") + 1);
        devname = devname.Substring(0, devname.IndexOf(" "));

        devteam = TitleText.Substring(TitleText.IndexOf("!") + 1);
        devteam = devteam.Substring(0, devteam.IndexOf(" "));

这些数据将被输入一个网站，用于任务管理和管理员将进入这个。。。 这样一来，它就成为管理员快速进入任务的工具

        string TitleText = "Hello @Sunil you are going to work on #Desktop which has a priority of !1 ";
        string title;
        string devname;
        string devteam;

        title = TitleText.Substring(TitleText.IndexOf("#")+1);
        title = title.Substring(0,title.IndexOf(" "));

        devname = TitleText.Substring(TitleText.IndexOf("@") + 1);
        devname = devname.Substring(0, devname.IndexOf(" "));

        devteam = TitleText.Substring(TitleText.IndexOf("!") + 1);
        devteam = devteam.Substring(0, devteam.IndexOf(" "));

我可以分割数据并对其进行处理……但是有太多的排列和组合可以输入顺序字符（#，@！）

        string TitleText = "Hello @Sunil you are going to work on #Desktop which has a priority of !1 ";
        string title;
        string devname;
        string devteam;

        title = TitleText.Substring(TitleText.IndexOf("#")+1);
        title = title.Substring(0,title.IndexOf(" "));

        devname = TitleText.Substring(TitleText.IndexOf("@") + 1);
        devname = devname.Substring(0, devname.IndexOf(" "));

        devteam = TitleText.Substring(TitleText.IndexOf("!") + 1);
        devteam = devteam.Substring(0, devteam.IndexOf(" "));

我试过这样的方法，但没用：

if (TitleText.Contains("#") && TitleText.Contains("@") && TitleText.Contains("!"))
{

        string[] arr = TitleText.Split('#', '@', '!');
        title = arr[0];
        devName = arr[1].Trim().ToLower();
        devTeam = arr[2].Trim().ToLower();
        prio = Convert.ToInt32(arr[3]);
    } else if (TitleText.Contains("#") && TitleText.Contains("@")) {
        string[] arr = TitleText.Split('#', '@');
        title = arr[0];
        devName = arr[1].Trim().ToLower();
        devTeam = arr[2].Trim().ToLower();
        // prio = Convert.ToInt32(arr[3]);
    } else if (TitleText.Contains("#") && TitleText.Contains("!")) {
        string[] arr = TitleText.Split('#', '!');
        title = arr[0];
        devName = arr[1].Trim().ToLower();
        //devTeam = arr[2];
        prio = Convert.ToInt32(arr[2]);
    } else if (TitleText.Contains("@") && TitleText.Contains("!")) {
        string[] arr = TitleText.Split('@', '!');
        title = arr[0];
        // devName = arr[1];
        devTeam = arr[1].Trim().ToLower();
        prio = Convert.ToInt32(arr[2]);
    } else if (TitleText.Contains("#")) {
        string[] arr = TitleText.Split('#');
        title = arr[0];
        devName = arr[1].Trim().ToLower();
        //devTeam = arr[1];
        //prio = Convert.ToInt32(arr[2]);
    } else if (TitleText.Contains("@")) {
        string[] arr = TitleText.Split('@');
        title = arr[0];
        // devName = arr[1];
        devTeam = arr[1].Trim().ToLower();
        //prio = Convert.ToInt32(arr[2]);
    } else if (TitleText.Contains("!")) {
        string[] arr = TitleText.Split('!');
        title = arr[0];
        // devName = arr[1];
        //devTeam = arr[1];
        prio = Convert.ToInt32(arr[1]);
    }

        string TitleText = "Hello @Sunil you are going to work on #Desktop which has a priority of !1 ";
        string title;
        string devname;
        string devteam;

        title = TitleText.Substring(TitleText.IndexOf("#")+1);
        title = title.Substring(0,title.IndexOf(" "));

        devname = TitleText.Substring(TitleText.IndexOf("@") + 1);
        devname = devname.Substring(0, devname.IndexOf(" "));

        devteam = TitleText.Substring(TitleText.IndexOf("!") + 1);
        devteam = devteam.Substring(0, devteam.IndexOf(" "));

如果每个句子都有多个标记，这将不起作用。但它确实与您提供的示例相反：

        string TitleText = "Hello @Sunil you are going to work on #Desktop which has a priority of !1 ";
        string title;
        string devname;
        string devteam;

        title = TitleText.Substring(TitleText.IndexOf("#")+1);
        title = title.Substring(0,title.IndexOf(" "));

        devname = TitleText.Substring(TitleText.IndexOf("@") + 1);
        devname = devname.Substring(0, devname.IndexOf(" "));

        devteam = TitleText.Substring(TitleText.IndexOf("!") + 1);
        devteam = devteam.Substring(0, devteam.IndexOf(" "));

试试正则表达式

        string TitleText = "Hello @Sunil you are going to work on #Desktop which has a priority of !1 ";
        string title;
        string devname;
        string devteam;

        title = title.Substring(0,title.IndexOf(" "));

        devname = TitleText.Substring(TitleText.IndexOf("@") + 1);
        devname = devname.Substring(0, devname.IndexOf(" "));

        devteam = TitleText.Substring(TitleText.IndexOf("!") + 1);
        devteam = devteam.Substring(0, devteam.IndexOf(" "));

string Name=Regex.Match(SubjectString, "@(.*?) ").Groups[1].Value;
string Comp=Regex.Match(SubjectString, "#(.*?) ").Groups[1].Value;
string Priort=Regex.Match(SubjectString, "!(.*?) ").Groups[1].Value;

如果任何搜索的字符不存在，这将抛出一个错误。@gbianchi-是的，它将抛出一个错误。在解析之前，添加条件逻辑来检查字符是否存在是不重要的。如果任何搜索的字符不存在，这将抛出一个错误。@gbianchi-是的，它将，在解析之前，添加条件逻辑来检查字符是否存在是很简单的。
