C＃不能访问从同一类文本框 [英] c# cannot access textboxes from same class

问题描述

我有两个独立的问题;然而，由于它们是非常相似的，我会要求他们在一个张贴。

i have two separate questions; however, since they are very similar i will ask them in one posting.

什么是我不能从这里引用文本框的原因是什么？我创建了另一个文件在我的项目，并把

what is the reason i cannot reference the textboxes from here? i created another file in my project and put

namespace EnterData.DataEntry
{
    public partial class WebForm1 : System.Web.UI.Page
    { 

，使其进入同一个命名空间和部分类作为网络表单。但我不能访问文本框！

to make it go into the same namespace and partial class as the webform. but i cannot access the textbox!

public partial class WebForm1 : System.Web.UI.Page
    {

public class LOMDLL.Main_Lom_Form PopulateMainForm()
        {
            //populate class
            LOMDLL.Main_Lom_Form TheForm = new LOMDLL.Main_Lom_Form();

            try
            {
                TheForm.lom_number = lom_numberTextBox.Text.ToInt();
                TheForm.identified_by = identified_byTextBox.Text;
                TheForm.occurrence_date = occurrence_dateTextBox.Text.ToDateTime();
                //TheForm.pre_contact = pre_contactTextBox.Text; //need to create this texdtbox
                //TheForm.pre_practice_code = pre_practice_codeTextBox.Text; //create this
                TheForm.report_by = report_byTextBox.Text;
                TheForm.report_date = report_dateTextBox.Text.ToDateTime();
                TheForm.section_c_comments = section_c_commentsTextBox.Text;
                TheForm.section_c_issue_error_identified_by = section_c_issue_error_identified_byTextBox.Text;
                TheForm.section_d_investigation = section_d_investigationTextBox.Text;
                TheForm.section_e_corrective_action = section_e_corrective_actionTextBox.Text;
                TheForm.section_f_comments = section_f_commentsTextBox.Text;
            }
            catch (Exception e)
            {

            }

我得到这个错误：

i get this error:

埃罗 R 20无法访问外部类型EnterData.DataEntry.WebForm1通过嵌套类型EnterData.DataEntry.WebForm1.LOMDLL'C的非静态成员：\\ Documents和Settings \\ agordon \\我的文档\\ Visual Studio 2008的\\项目\\ lomdb \\ EnterData \\ DataEntry \\ DAL.cs 68 38 EnterData

所有的文本框

什么是我不能从这里访问文本框的原因是什么？

what is the reason that i cannot access the textboxes from here?

推荐答案

您的意思是在这里筑巢类？如果您打算声明返回 Main_Lom_Form（），试试这个方法：

Did you mean to nest classes here? If you intended to declare a method that returns a Main_Lom_Form(), try this:

public LOMDLL.Main_Lom_Form PopulateMainForm()

如果您打算调用该方法对 WebForm1的的成员名为 TheForm ，然后实例化的那个之外来电 PopulateMainForm ：

If you intended to call that method against a member of WebForm1 called TheForm, then instantiate that outside of the call to PopulateMainForm:

LOMDLL.Main_Lom_Form TheForm = new LOMDLL.Main_Lom_Form();
public void PopulateMainForm()
{
    // snip
}
