C#读取oracle数据问题

Question

试试 (bool)字段名

Answer 1

Oracle里没有Ｂool这个类型啊

Answer 2

Checked='<%#DataBinder.Eval(Container.DataItem,"数据库字段").ToString()=="1"%>'> 

Answer 3

我的办法比较笨，希望对你有用。就是把那一列转换为模板列，删除原来的控件，添加一个label和一个checkBox，
label单向绑定那个字段。运行时的代码如下：
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        Label lbl1;
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if (e.Row.RowState == DataControlRowState.Edit || (e.Row.RowState == (DataControlRowState)5))
            {
                lbl1 = (Label)e.Row.Cells[6].Controls[1];
                lbl1.Visible = false;
                CheckBox cb1 = (CheckBox)e.Row.Cells[6].Controls[3];
                try
                {
                    int i1 = int.Parse(lbl1.Text);
                    if (i1 > 0) cb1.Checked = true;
                    else cb1.Checked = false;
                }
                catch
                {
                    cb1.Checked = false;
                }
            }
        }
    }

Answer 4

直接绑定上去就可以了.
                                    <Columns>
                                        <asp:TemplateField>
                                            <HeaderStyle CssClass="CheckColumn" />
                                            <ItemStyle CssClass="CheckColumn" />
                                            <ItemTemplate>
                                                <asp:CheckBox ID="asp_chbIsChecked" Checked='<%# DataBinder.Eval(Container, "DataItem.IsChecked") %>' runat="server" />                                        
                                            </ItemTemplate>
                                        </asp:TemplateField></Columns>
后台绑定就行了.
