如果我的计算机上运行着2个x = 1.283
ax = plt.subplot(1, 1, 1)
setup(ax)
movepoint = ax.plot(x, 0.02, 'rv')
plt.pause(1)
while x <= 1.3:
movepoint.remove()
x += 0.001
movepoint = ax.plot(x, 0.02, 'rv')
plt.pause(0.000001)
plt.show()
网站，并且打开了2个Asp.Net窗口，那么有多少个静态类PowerShell实例？
每台机器一个？每个应用程序域一个？每个进程一个？
答案 0 :(得分：0)
文档中没有任何内容表明List<User_controls> ctrl = new List<User_controls>();
protected void Page_Load(object sender, EventArgs e)
{
Session["userid"] = 3;
CreateControls();
}
protected void CreateControls()
{
if (!IsPostBack)
{
if (ViewState["totalcount"] == null)
{
ViewState["oldcount"] = ViewState["totalcount"] = 1;
}
}
for (int i = 0; i < (int)ViewState["totalcount"]; i++)
{
ctrl.Add((User_controls)LoadControl("~/User/controls.ascx"));
int index = ctrl.Count - 1;
pnl.Controls.Add(ctrl[index]);
ctrl[index].ID = "ctrl " + index;
ctrl[index].ehclick += new EventHandler(this.Btncancel_Click);
}
}
protected void btnadd_Click(object sender, EventArgs e)
{
int count = 0;
if (ViewState["newcount"] != null)
count = (int)ViewState["newcount"];
count++;
ViewState["newcount"] = count;
ViewState["totalcount"] = (int)ViewState["newcount"] + (int)ViewState["oldcount"];
ctrl.Add((User_controls)LoadControl("~/User/controls.ascx"));
pnl.Controls.Add(ctrl[ctrl.Count() - 1]);
ctrl[ctrl.Count() - 1].ID = "ctrl " + (ctrl.Count() - 1);
ctrl[ctrl.Count() - 1].ehclick += new EventHandler(this.Btncancel_Click);
}
protected void Btncancel_Click(object sender, EventArgs e)
{
User_controls rmctrl = (User_controls)sender;
int index = ctrl.IndexOf(rmctrl);
pnl.Controls.Remove(ctrl[index]);
ctrl.RemoveAt(index);
if (index < (int)ViewState["oldcount"])
{
ViewState["oldcount"] = (int)ViewState["oldcount"] - 1;
}
else
ViewState["newcount"] = (int)ViewState["newcount"] - 1;
if (ViewState["newcount"] != null)
{
ViewState["totalcount"] = (int)ViewState["newcount"] + (int)ViewState["oldcount"];
}
else
ViewState["totalcount"] = (int)ViewState["oldcount"];
}
实例不是标准静态实例。
应遵循正常规则：应用程序域被销毁时，它会被销毁，我们推断每个应用程序域都有一个。
您可以通过打开两个Powershell Windows并输入
来验证ServicePointManager
PowerShell其中之一和
[System.Net.ServicePointManager]::DefaultConnectionLimit--; [System.Net.ServicePointManager]::DefaultConnectionLimit
在另一个。
