可怕的异常

[asflhalwihfilaa]

未处理的“System.StackOverflowException”类型的异常出现在 mscorlib.dll 中。

错误代码如下：_header = (friendsheader)LoadControl(Request.ApplicationPath + Path.AltDirectorySeparatorChar+"contorls/friendsheader.ascx");

override protected void OnInit(EventArgs e)
{
//
// CODEGEN: 该调用是 ASP.NET Web 窗体设计器所必需的。
//

_header = (friendsheader)LoadControl(Request.ApplicationPath + Path.AltDirectorySeparatorChar+"contorls/friendsheader.ascx");
_subheader = new SubHeader();
Page.Controls.AddAt(0,_header);
Page.Controls.AddAt(0,_subheader);
InitializeComponent();
base.OnInit(e);
}

StackOverflowException 因执行堆栈溢出错误引发，通常在存在非常深的递归或无界递归时发生。

检查一下是否存在非常深的递归或无界递归

是否有什么数组越界之类的代码 查查看

帮我看看哪里出错了啊～我找不到

[humin1906]

晕，这么多的代码一起上了，
单步调式看哪里错了。

[asflhalwihfilaa]

复制进去帮我看看啊～谢谢！！！
