写入NameValueCollection

Question

我正在尝试实现一个简单的构造，首先清除NameValueCollection并向其写入新值。然而，目前我不能，因为它是只读的。有没有办法让它不再只读或者四处走动？我的代码：

NameValueCollection DataDictionary = ConfigurationManager.GetSection("dataDictionary") as NameValueCollection;
            DataDictionary.Clear();
            for (int i = 0; i < tableLayoutPanel2.RowCount; i++)
            {
                var T = tableLayoutPanel2.GetControlFromPosition(1, i);
                var T2 = tableLayoutPanel2.GetControlFromPosition(3, i);
                string key = T.Text;
                string value = T2.Text;
                DataDictionary.Add(key, value);
            }

Answer 1

将其复制到new NameValueCollection中

var writableCollection = new NameValueCollection(DataDictionary);
writableCollection.Add(...);
