单选按钮选中不触发

Question

我有一个单选按钮

 <asp:RadioButton ID="AMRadioButton" runat="server" AutoPostBack="True" GroupName="TypeGroup"
                                OnCheckedChanged="AMRadioButton_CheckedChanged" Text="Accounting Date" />
                            <asp:RadioButton ID="LMRadioButton" runat="server" AutoPostBack="True" GroupName="TypeGroup"
                                OnCheckedChanged="LMRadioButton_CheckedChanged" Text="Loan Date" />

我有一个代码

 protected void AddButton_Click(object sender, EventArgs e)
    {
        if (AMRadioButton.Checked = true)
        {
            prenda.Bcode = BranchCodetxtbox.Text;
            prenda.AccountingMonth = YearDropDownList.SelectedValue + "/" + MonthDropDownList.SelectedValue;
            prenda.Jprincipal = Convert.ToDecimal(JewelryTextBox.Text);
            prenda.Aprincipal =  Convert.ToDecimal(ApplianceTextBox.Text);
            prenda.Cprincipal =  Convert.ToDecimal(CellphoneTextBox.Text);
            user.UserID = Session["UserID"].ToString();
            servs.UploadPrendaAM(prenda, user);
            Session["Count"] = "1";
            Response.Write("<script language='javascript'>window.alert('Success!');window.location='DataEntryPage.aspx';</script>");

        }
        else if (LMRadioButton.Checked = true)
        {
            prenda.Bcode = BranchCodetxtbox.Text;
            prenda.LoanMonth = YearDropDownList.SelectedValue + "/" + MonthDropDownList.SelectedValue;
            prenda.Jprincipal =  Convert.ToDecimal(JewelryTextBox.Text);
            prenda.Aprincipal =  Convert.ToDecimal(ApplianceTextBox.Text);
            prenda.Cprincipal =  Convert.ToDecimal(CellphoneTextBox.Text);
            user.UserID = Session["UserID"].ToString();
            servs.UploadPrendaLM(prenda, user);
            Session["Count"] = "1";
            Response.Write("<script language='javascript'>window.alert('Success!');window.location='DataEntryPage.aspx';</script>");

        }
    }

问题是即使我已经检查/选择LMradiobutton代码仍然进入if(AMRadioButton.Checked = true)这不是我想要的，当然我勾选LMradiobutton代码应该是else if (LMRadioButton.Checked = true)这里没有amradiobutton.Checked。

我错过了什么吗？ 请帮忙

Answer 1

采用

if(AMRadioButton.Checked == true) 

要么

else if (LMRadioButton.Checked == true)

使用==检查条件或比较运算符

分配值时使用=。

您正在为已检查的属性赋值，该属性将始终返回true。
