问题描述
我有一个网页表单，上面有一个打印按钮。打印按钮根据三个文本框的值打印出四种不同的报告。
这是打印按钮代码：
if （Page.IsValid）
{
int iTextBoxFTE40 = Convert.ToInt32（TextBoxFTE40.Text）;
int iTextBoxHC50 = Convert.ToInt32（TextBoxHC50.Text）;
int iTextBoxFTE4050 = Convert.ToInt32（TextBoxFTE4050）;
if （iTextBoxFTE40 > 40 ）
{
TextBoxINST_ID.Text =会话[ inst_id< /跨度>]的ToString（）;
ClientScript.RegisterStartupScript（ this .GetType（）， onclick， < script language = javascript> window.open（'ReportFormFTE40.aspx ， 'PrintMe'， '身高= 650像素，宽= 950像素，滚动条= 1'）;< /脚本>中）;
ScriptManager.RegisterStartupScript（ this ， typeof （页面）， myscript， alert（'您已成功提交了General和Enrollment Profile的电子部分。请将您签名的Profile以及任何所需的附件发送到SACSCOC，Attn：Profiles，1866 Southern Lane，Decatur，Ga 30033。'）; location.href = 'WelcomeMenu.aspx';， true ）;
}
其他 if （iTextBoxHC50 > 50 ）
{
TextBoxINST_ID.Text = Session [ inst_id]。ToString（）;
ClientScript.RegisterStartupScript（ this .GetType（）， onclick， < script language = javascript> window.open（'ReportFormFTE50.aspx ， 'PrintMe'， '身高= 650像素，宽= 950像素，滚动条= 1'）;< /脚本>中）;
ScriptManager.RegisterStartupScript（ this ， typeof （页面）， myscript， alert（'您已成功提交了General和Enrollment Profile的电子部分。请将您签名的Profile以及任何所需的附件发送到SACSCOC，Attn：Profiles，1866 Southern Lane，Decatur，Ga 30033。'）; location.href = 'WelcomeMenu.aspx';， true ）;
}
else if （iTextBoxFTE4050 > 90 ）
{
TextBoxINST_ID.Text = Session [ inst_id]。ToString（）;
ClientScript.RegisterStartupScript（ this .GetType（）， onclick， < script language = javascript> window.open（'ReportFormFTE4050.aspx ， 'PrintMe'， '身高= 650像素，宽= 950像素，滚动条= 1'）;< /脚本>中）;
ScriptManager.RegisterStartupScript（ this ， typeof （页面）， myscript， alert（'您已成功提交了General和Enrollment Profile的电子部分。请将您签名的Profile以及任何所需的附件发送到SACSCOC，Attn：Profiles，1866 Southern Lane，Decatur，Ga 30033。'）; location.href = 'WelcomeMenu.aspx';， true ）;
}
else
{
TextBoxINST_ID.Text = Session [ inst_id]。ToString（）;
ClientScript.RegisterStartupScript（ this .GetType（）， onclick， < script language = javascript> window.open（'ReportFormFTE.aspx ， 'PrintMe'， '身高= 650像素，宽= 950像素，滚动条= 1'）;< /脚本>中）;
ScriptManager.RegisterStartupScript（ this ， typeof （页面）， myscript， alert（'您已成功提交了General和Enrollment Profile的电子部分。请将您签名的Profile以及任何所需的附件发送到SACSCOC，Attn：Profiles，1866 Southern Lane，Decatur，Ga 30033。'）; location.href = 'WelcomeMenu.aspx';， true ）;
}
单击打印按钮时出现此错误：
无法将'System.Web.UI.WebControls.TextBox'类型的对象强制转换为'System.IConvertible'。
什么这是否意味着？它发生在这一行：
int iTextBoxFTE4050 = Convert.ToInt32（TextBoxFTE4050）;
如何解决这个问题？
解决方案
如果你不愿意阅读< a href =http://www.codeproject.com/Answers/837831/Print-different-reports-depending-on-Value-in-text> Chill60的回答 [ ^ ] to 您之前的这个问题的副本 [ ^ ]，你会知道答案：
int iTextBoxFTE4050 = Convert.ToInt32（TextBoxFTE4050.Text）;
I have a web form that has a print button on it. The print button prints out four different reports depending on the value of the three textboxes.
Here is the Print button code:
if (Page.IsValid)
{
int iTextBoxFTE40 = Convert.ToInt32(TextBoxFTE40.Text);
int iTextBoxHC50 = Convert.ToInt32(TextBoxHC50.Text);
int iTextBoxFTE4050 = Convert.ToInt32(TextBoxFTE4050);
if (iTextBoxFTE40 > 40)
{
TextBoxINST_ID.Text = Session["inst_id"].ToString();
ClientScript.RegisterStartupScript(this.GetType(), "onclick", "<script language=javascript>window.open('ReportFormFTE40.aspx','PrintMe','height=650px,width=950px,scrollbars=1');</script>");
ScriptManager.RegisterStartupScript(this, typeof(Page), "myscript", "alert('You have successfully submitted the electronic portion of the General and Enrollment Profile. Please send your signed Profile along with any required attachments to SACSCOC, Attn: Profiles, 1866 Southern Lane, Decatur, Ga 30033.');location.href='WelcomeMenu.aspx';", true);
}
else if (iTextBoxHC50 > 50)
{
TextBoxINST_ID.Text = Session["inst_id"].ToString();
ClientScript.RegisterStartupScript(this.GetType(), "onclick", "<script language=javascript>window.open('ReportFormFTE50.aspx','PrintMe','height=650px,width=950px,scrollbars=1');</script>");
ScriptManager.RegisterStartupScript(this, typeof(Page), "myscript", "alert('You have successfully submitted the electronic portion of the General and Enrollment Profile. Please send your signed Profile along with any required attachments to SACSCOC, Attn: Profiles, 1866 Southern Lane, Decatur, Ga 30033.');location.href='WelcomeMenu.aspx';", true);
}
else if (iTextBoxFTE4050 > 90)
{
TextBoxINST_ID.Text = Session["inst_id"].ToString();
ClientScript.RegisterStartupScript(this.GetType(), "onclick", "<script language=javascript>window.open('ReportFormFTE4050.aspx','PrintMe','height=650px,width=950px,scrollbars=1');</script>");
ScriptManager.RegisterStartupScript(this, typeof(Page), "myscript", "alert('You have successfully submitted the electronic portion of the General and Enrollment Profile. Please send your signed Profile along with any required attachments to SACSCOC, Attn: Profiles, 1866 Southern Lane, Decatur, Ga 30033.');location.href='WelcomeMenu.aspx';", true);
}
else
{
TextBoxINST_ID.Text = Session["inst_id"].ToString();
ClientScript.RegisterStartupScript(this.GetType(), "onclick", "<script language=javascript>window.open('ReportFormFTE.aspx','PrintMe','height=650px,width=950px,scrollbars=1');</script>");
ScriptManager.RegisterStartupScript(this, typeof(Page), "myscript", "alert('You have successfully submitted the electronic portion of the General and Enrollment Profile. Please send your signed Profile along with any required attachments to SACSCOC, Attn: Profiles, 1866 Southern Lane, Decatur, Ga 30033.');location.href='WelcomeMenu.aspx';", true);
}
When the Print button is clicked this error comes up:
Unable to cast object of type 'System.Web.UI.WebControls.TextBox' to type 'System.IConvertible'.
What does this mean? It happens on this line:
int iTextBoxFTE4050 = Convert.ToInt32(TextBoxFTE4050);
How can I fix this?
解决方案
If you'd bothered to read Chill60's answer[^] to your previous copy of this question[^], you'd know the answer:
int iTextBoxFTE4050 = Convert.ToInt32(TextBoxFTE4050.Text);
