Question

要求：我有一个用C＃编写的Windows应用程序，目前只能按1公司价值搜索.CSV文件（例如：按公司搜索：160）我希望它搜索多个公司由逗号分隔的值（例如：按公司搜索：160,220,310,550,610）。

问题：如何搜索逗号分隔的多个公司值？（例如：按公司搜索：160,220,310,550,610）。字符串必须用逗号值分割，当有x＃个逗号时，每个字符串的值必须设置为x + 1＃个变量（例如：Corp1，Corp2，Corp3）（例如：Corp1，Corp2，Corp3）有两个逗号，所以必须定义3个变量）然后为每个公司值循环搜索x + 1次

以下是 MainForm.cs 代码中的相关代码，其中定义了公司值：

    private SearchCriteria GetSearchCriteria()
    {

        // Initialize Search Parameters object
        SearchCriteria sc = new SearchCriteria(textBoxCorp.Text,
                                               textBoxOrderNumber.Text,
                                               textBoxCampaign.Text,
                                               textBoxCity.Text,
                                               comboBoxState.Text,
                                               textBoxZip.Text,
                                               folderBrowserDialog1.SelectedPath,
                                               folderBrowserDialog2.SelectedPath,
                                               radioButtonAny.Checked,
                                               radioButtonAll.Checked);

        return sc;
    }

    private void textBoxCorp_TextChanged(object sender, EventArgs e) { }

以下是 SearchProcess.cs 中的相关代码，其中引入了公司值并检查它是否与搜索匹配：

    // Function runs in worker thread and emulates long process.
    public void Run()
    {
        m_sc = (SearchCriteria)m_form.Invoke(m_form.m_DelegateGetSearchCriteria);
        // Display parameters
        m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search on Corp: " + m_sc.get_Corp() });
        m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search on OrderNumber: " + m_sc.get_OrderNumber() });
        m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search on Campaign: " + m_sc.get_Campaign() });
        m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search on City: " + m_sc.get_City() });
        m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search on State: " + m_sc.get_State() });
        m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search on Zip: " + m_sc.get_Zip() });
        m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search on Source Path: " + m_sc.get_SourcePath() });
        m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search on Target Path: " + m_sc.get_TargetPath() });
        if (m_sc.get_SearchAND()==true)
        {
            m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search for All" });
        }
        else
        {
            m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search for Any" });
        }

            // Found should be true if ANY of the criteria are met. 
            // This is an OR logic gate
            // If any of the given fields do match then it is a true
            if (m_sc.get_SearchOR().Equals(true))
            {
                // Check for the Corp type match
                if (m_sc.get_Corp() != "" && String.Compare(AgentID, m_sc.get_Corp()) == 0)
                {
                    found = true;
                }
        }

            // Copy the file if ANY of the search criteria have been met
            if (found)
            {

                m_form.Invoke(m_form.m_DelegateAddString, new Object[] {"FOUND: Order_No: " + Order_No +
                                                                        " barcode: " + barcode +
                                                                        " MailerCode: " + MailerCode +
                                                                        " AgentID: " + AgentID +
                                                                        " City: " + City +
                                                                        " State: " + State +
                                                                        " ZIP: " + ZIP});
                //passes values to TransferFile 
                TransferFile(directory, barcode, AgentID, ZIP);
            }
        } // end for that finds each matching record

任何帮助将不胜感激！谢谢！！！

不完全确定您在做什么，您搜索的数据源在哪里，所以只是猜测：

string sCorpFilter = m_sc.get_Corp();
IEnumerable<string> corps = null;

if (! string.IsNullOrEmpty(sCorpFilter))
{
  corps = sCorpFilter.Split(",".ToCharArray(),
   StringSplitOptions.RemoveEmptyEntries).Select(s => s.Trim());
}
[...]
if (corps != null && corps.Contains(AgentID))
{
  found = true;
}

C＃ - 使用String Splitter查询多个逗号分隔值搜索参数
