Question

我从.csv文件获取值并将它们放入datagridview，但我想在填充datagridview之前替换一些值。

这是我的.csv文件的屏幕：

这是我尝试这样做的代码：

string FileName = @"C:\mydir\testcsv.csv";
    OleDbConnection conn = new OleDbConnection
           ("Provider=Microsoft.Jet.OleDb.4.0; Data Source = " +
             Path.GetDirectoryName(FileName) +
             "; Extended Properties = \"Text;HDR=YES;FMT=Delimited\"");

    conn.Open();

    OleDbDataAdapter adapter = new OleDbDataAdapter
           ("SELECT * FROM " + Path.GetFileName(FileName), conn);

    DataSet ds = new DataSet("Temp");
    adapter.Fill(ds);

    conn.Close();

    DataTable dt = ds.Tables[0];

    List<HT> matchhtList = new List<HT>();
    matchhtList = (from DataRow dr in dt.Rows
                   select new HT()
                   {
                       Home = dr["Home"].ToString(),
                       Away = dr["Away"].ToString(),
                       ScoreHome = dr["ScoreHome"].ToString(),
                       ScoreAway = dr["ScoreAway"].ToString(),
                       Segno = dr["Segno"].ToString(),
                       odd1 = dr["odd1"].ToString(),
                       oddx = dr["oddx"].ToString(),
                       odd2 = dr["odd2"].ToString()

                   }).ToList();

    StringBuilder mystring = new StringBuilder("matchhtList");
    mystring = mystring.Replace("Rosenborg", "Rihanna")
           .Replace("Start", "Stop")
           .Replace("Brann", "Circus");

    dataGridView2.DataSource = mystring;

请问，如果我的问题不明确，请在告诉我之前加上“-1”，我会尝试更好地解释我的问题。非常感谢你！

您可以在构建列表时替换文本

matchhtList = (from DataRow dr in dt.Rows
                   select new HT()
                   {
                       Home = dr["Home"].ToString().Replace("Rosenborg", "Rihanna"),
                       Away = dr["Away"].ToString().Replace("Start", "Stop").Replace("Brann", "Circus"),
                       ScoreHome = dr["ScoreHome"].ToString(),
                       ScoreAway = dr["ScoreAway"].ToString(),
                       Segno = dr["Segno"].ToString(),
                       odd1 = dr["odd1"].ToString(),
                       oddx = dr["oddx"].ToString(),
                       odd2 = dr["odd2"].ToString()

                   }).ToList();

dataGridView2.DataSource = matchhtList;

Answer 2

您可以操纵gridview <{1}}事件中的值

https://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.rowdatabound(v=vs.110).aspx

您的rowdatabound必须是上述情景中的列表或datasource。

DataTable

应该是

dataGridView2.DataSource = mystring;//Wrong
