1、常用调用方法

2、获取指定窗体内，所以check值集合
1 /// <summary> 2 /// 加载公司组件 3 /// </summary> 4 private void LoadCompanyComponent() 5 { 6 HRPOWER.BLL.Company _ocompany = new HRPOWER.BLL.Company(); 7 DataTable _dt = _ocompany.GetCompanyInfo(); 8 9 int LOCATIONX = 218; 10 11 if (_dt.Rows.Count > 0) 12 { 13 for (int i = 0; i < _dt.Rows.Count; i++) 14 { 15 Parts.UCRightCompany _ucRC = new HRPOWER.WIN.UC.Parts.UCRightCompany(); 16 _ucRC.COMPANYNAME = _dt.Rows[i]["NAME_SHORT"].ToString(); 17 _ucRC.COMPANYID = _dt.Rows[i]["ID"].ToString(); 18 Control c = (Control)_ucRC; 19 c.Location = new Point(LOCATIONX, LOCATIONY); 20 c.Name = "UCRightCompany" + i.ToString(); 21 this.Controls.Add(c); 22 LOCATIONX += 129; 23 } 24 } 25 if (LOCATIONX > this.Width) 26 { 27 this.Width = LOCATIONX + _dt.Rows.Count; 28 } 29 } 30 31 /// <summary> 32 /// 获取用户对应的权限 33 /// </summary> 34 /// <param name="cContainer">控件容器</param> 35 private void SearchControls(System.Windows.Forms.Control cContainer) 36 { 37 foreach (System.Windows.Forms.Control c in cContainer.Controls) 38 { 39 if (c is CheckBox) 40 { 41 CheckBox _chb = (CheckBox)c; 42 if (_chb.Checked) 43 { 44 string _sCompID = String.Empty; 45 Control[] ctlList = _chb.Parent.Parent.Controls.Find("chbCompany", true); 46 47 if (ctlList.Length > 0) 48 { 49 CheckBox chb = (CheckBox)ctlList.GetValue(0); 50 _sCompID = chb.Text; 51 52以上是关于WinForm 遍历用户控件里CheckBox的主要内容，如果未能解决你的问题，请参考以下文章
c# winfrom。有4个 checkBox控件，如何判断只要选中，就把选中的checkbox的内容放一起显示出来？
