找出窗体中指定控件(WINFORM && WEBFORM)

遍历WINFORM当前窗体所有控件

foreach (Form form in Application.OpenForms)

{

foreach (Control item in form.Controls)

{

if (item is TextBox)

{

TextBox tb = (TextBox)item;

tb.Text = "Somtething";

}

}

}

遍历WEBFORM窗体所有控件

for (int i = 0; i < this.Controls.Count; i++)

{

foreach (Control o in Page.Controls[i].Controls)

{

if (o is TextBox)

{

TextBox tb = (System.Web.UI.WebControls.TextBox)o;

tb.Text = "Some";

}

}

}
