Question

我有一个代码，可以通过电子邮件发送datagridview上可见的所有内容。我希望它删除任何列为“未结头寸”的人，然后将所有人的姓名放入电子邮件TO部分。

任何帮助将不胜感激！

这是我到目前为止的代码....

 try
 {
     String str = "", str1 = "";
     for (int i = 0; i < dataGridView1.RowCount; i++)
     {
         str1 = dataGridView1.Rows[i].Cells["C1"].Value.ToString();
         if (!str.Contains(str1)) str += str1 + ";";
         str1 = dataGridView1.Rows[i].Cells["C2"].Value.ToString();
         if (!str.Contains(str1)) str += str1 + ";";

         Microsoft.Office.Interop.Outlook.Application outlookApp = new Microsoft.Office.Interop.Outlook.Application();
         Microsoft.Office.Interop.Outlook.MailItem mailItem = (Microsoft.Office.Interop.Outlook.MailItem);  
         outlookApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);
         mailItem.To = str;
         mailItem.Importance = Microsoft.Office.Interop.Outlook.OlImportance.olImportanceLow;
         mailItem.Display(false);

     }
 }

使用Linq

// get c1 cell values to a list
var c1 = dataGridView1.Rows.Cast<DataGridViewRow>()
    .Select(row => row.Cells["C1"].Value.ToString()).ToList();

// get c2 cell values to a list
var c2 = dataGridView1.Rows.Cast<DataGridViewRow>()
    .Select(row => row.Cells["C2"].Value.ToString()).ToList();

// remove duplicates and join them and assign 
mailItem.To = string.Join(";", c1.Union(c2).ToArray());

如果您有任何其他列值决定选择单元格值，您只需添加条件和过滤器记录，如下所示

// get c1 cell values to a list
var c1 = dataGridView1.Rows.Cast<DataGridViewRow>()
    .Where(r=>r.Cells["Name"].Value.ToString() != "open")
    .Select(row => row.Cells["C1"].Value.ToString()).ToList();

C＃remove如果datagridview单元格具有特定文本
