Question

在Windows 7上使用Windows窗体在Visual Studio 2017中获取以下错误。这种情况发生在多台计算机上。我在标签中有一组编辑框，所有这些编辑框都设置为隐藏或在选择＆＃34;表格时可见。在一个组合框中。发生的事情是我将文本导入这些编辑框，滚轮滚动或向上/向下箭头，通过形式组合框选择要显示或隐藏的不同标签，这样做最终这些形式之一的编辑框变为空白。当您输入编辑框时，会出现内存错误。我搜索并搜索了一个没有运气的解决方案。任何帮助都会非常感激。

导入编辑框的代码为空白。

List<string> ort = imp.Split(new[] { Environment.NewLine }, StringSplitOptions.None).ToList();
//Name regex match
var match = new Regex(@"((?<=: ).*(?=\[))");
var name = match.Match(ort[0]);
if (tChoice == 0) { user.Text = String.Empty; user.AppendText(name.Groups[0].ToString()); }
if (tChoice == 1) { pwuser.Text = String.Empty; pwuser.AppendText(name.Groups[0].ToString()); }
if (tChoice == 2)
{
    gmmuser.Text = String.Empty; requser.Text = String.Empty; reqAuser.Text = String.Empty; billuser.Text = String.Empty;
    gmmuser.AppendText(name.Groups[0].ToString()); requser.AppendText(name.Groups[0].ToString()); reqAuser.AppendText(name.Groups[0].ToString()); billuser.AppendText(name.Groups[0].ToString());
}
if (tChoice == 3) { emailuser.Text = String.Empty; emailuser.AppendText(name.Groups[0].ToString()); }

实际上看起来它可能与目标框架有关。我把它设置为4.6.2。我把它设置为4.5.2并且尚未遇到问题，手指交叉。
