用workbuddy自定义Skill：手把手搭建AI炒股分析助手 AI Agent正成为个人投资研究的重要工具，而Skill作为行为规范，能让AI输出保持稳定与专业。在AI Agent应用中，很多人分不清Skill与Agent的区别：Agent负责目标拆解与执行，Skill则固化分析流程与输出模板。借助本地工作台workbuddy，用户可自定义Skill，实现从市场环境检查到财务排雷的五段式分析。通过调低温度参数、设定数据验证规则，该方案能有效避免大模型凭空编造数据，帮助个人投资者快速完成基本面体检、资金面观察与风险清单生成。本文基于一套可直接套用的配置与一个月实测，展示阅读详情

PayrollEdit("add", intRowsIndex,3);

this.Table1.FindControl("textid0").Focus();

protected void PayrollEdit(string str,int intRowsIndex,int js)
{
if (str == "add")
{
//获得数据表
DataTable T_Yuan_payrolls = (DataTable)Session["T_Yuan_payrolls"];
String Edit_date = T_Yuan_payrolls.Rows[intRowsIndex]["Date"].ToString();
String Edit_Name = T_Yuan_payrolls.Rows[intRowsIndex]["Name"].ToString();

//建立数据源
Yuan_PayrollsEdit yuan_payrollsEdit = new Yuan_PayrollsEdit();
DataSet ds_Yuan_payrollsEdit = yuan_payrollsEdit.GetDataSet(Edit_date, Edit_Name);

string aa = ds_Yuan_payrollsEdit.Tables["T_Yuan_payrollsEdit_add"].Rows.Count.ToString();
TableRow tr = new TableRow();
TableCell tc;
TableCell cell;
TextBox tc1;
int i = 0;
decimal sum_je = 0.00m;
for (i = 0; i < int.Parse(aa); i++)
{
if (i == 0)
{
tr = new TableRow();

//tr = new TableRow();
tc = new TableCell();
cell = new TableCell();
Label tcc = new Label();
Label tcc1 = new Label ();
tc.ID = "labeltop";//发放日期
tcc.ID = "tlbtop";//发放姓名
tcc1.ID = "labeladd";//发放项目计数
tc.Text = Edit_date;
tcc.Text = Edit_Name;
tcc1.Text = aa;
//tcc1.Visible = false;
tcc1.ForeColor = Color.White;
tc.CssClass = "c_label";

//tcc1.CssClass = "C_label_Visible";
tr.Cells.Add(tc);
cell.Controls.Add(tcc);
cell.Controls.Add(tcc1);
tr.Cells.Add(cell);
Table1.Rows.Add(tr);

}
if (i % js == 0)
tr = new TableRow();

tc = new TableCell();
//tc.ID = "Label" + ds_Yuan_payrollsEdit.Tables["T_Yuan_payrollsEdit_add"].Rows[i][0].ToString();
tc.ID = "label" + i.ToString();
cell = new TableCell();
tc1 = new TextBox();
tc1.ID = "textid" + i.ToString();
tc1.Columns = 8;
tc1.CssClass = "c_textbox";
tc.CssClass = "c_label";
tc1.Text = ds_Yuan_payrollsEdit.Tables["T_Yuan_payrollsEdit_add"].Rows[i][2].ToString();
sum_je += decimal.Parse(ds_Yuan_payrollsEdit.Tables["T_Yuan_payrollsEdit_add"].Rows[i][2].ToString());
tc.Text = ds_Yuan_payrollsEdit.Tables["T_Yuan_payrollsEdit_add"].Rows[i][1].ToString() + "： ";
//var tlbID = Table1.FindControl("Label_add").ClientID;
//tc1.Attributes.Add("onkeydown", "return CheckInput(this.value,tlbID)");
tc1.Attributes.Add("onkeydown", "return CheckInput()");
//tc1.Attributes.Add("onkeydown", "return CheckInput(this.value,this.ID)");
tr.Cells.Add(tc);
cell.Controls.Add(tc1);
tr.Cells.Add(cell);
if (i % js == 0)
{
Table1.Rows.Add(tr);
}
}
if (i % js != 0)
Table1.Rows.Add(tr);

tr = new TableRow();
tc = new TableCell();
tc.ID = "labelsum";
cell = new TableCell();
Label sum_tcc = new Label();
Label sum_tcc1 = new Label();
sum_tcc.ID = "tlbsum";
tc.Text = "小计：";
sum_tcc.Width = 95;
sum_tcc.Text = sum_je.ToString();
sum_tcc1.Text = aa;
//sum_tcc1.Visible = false;
sum_tcc1.ForeColor = Color.White;
tc.CssClass = "c_label_sum";
sum_tcc.CssClass = "c_label_sum";
tr.Cells.Add(tc);
cell.Controls.Add(sum_tcc);
cell.Controls.Add(sum_tcc1);
tr.Cells.Add(cell);
Table1.Rows.Add(tr);
}

通过PayrollEdit 函数根据后台数据产生自动产生一堆 Label 和 Textbox

然后通过 this.Table1.FindControl("textid0").Focus(); 让第一个控件获得焦点

我原本想通过 this.Table1.FindControl("textid0").selectAll(); 让控件获得焦点的同时选取控件的所有文本

可实际 this.Table1.FindControl("textid0") 没有 selectAll() 这个函数

请问我该如何写才能让控件获得焦点的同时选取控件的所有文本谢谢！
