try
            {
                int k = 0;
                mobiletxt.Text = "";
                foreach (DataRowView  item in checkedListView.SelectedItems)

                    k = k + 1;
                }
            }
            catch (Exception) { }

该代码运行了20000次，因为它位于foreach na中，
这是我遇到的两个错误，95％即将发生，而另外5％则未发生，这意味着什么，请帮帮我.
在此先感谢

推荐答案

嗨
CLR允许对象的总大小不超过2147483647字节，但是字符串只占该大小的一半，即1073741823个字符，这是因为字符串中的每个字符都占用2个字节..

因此，我想没有一个控件会通过使用字符串数据类型在单个控件中显示这么多数据

您的代码有几个问题，我更改了代码...所以请尝试使用此

Hi
CLR will allow having object size not more than 2147483647 bytes total, But string will take only by half of this size i.e 1073741823 characters and this is because of each character in string eats up 2 bytes..

So, I guess no control shows this much data in single control by means of using string datatype

There are few issues with your code, i changed the code...so try with this

mobiletxt.Text = "";
                var listValues = new List<string>();
                foreach (DataRowView item in checkedListView.SelectedItems)
                {
                    string temp = item.Row.ItemArray[1].ToString();
                    if (!string.IsNullOrEmpty(temp))
                    {
                        listValues.Add(temp);
                    }
                }
                mobiletxt.Text = string.Join(",", listValues.ToArray());
</string>

错误在这里:

Error is here:

mobiletxt.Text = mobiletxt.Text + "," + s.ToString();

mobiletxt.Text

无法容纳更多数据.
删除此

can''t hold more data.
Remove this

mobiletxt.Text = mobiletxt.Text + "," + s.ToString();

行再次运行，不会出现相同的错误.

line run again and there will not be that same error.
