推荐答案

string fname="", lname="", faname="",mname="";
fname = textBox1.Text.ToString();
lname = textBox2.Text.ToString();
faname = textBox3.Text.ToString();
mname = textBox4.Text.ToString();
//you ll not find double entry in your list box
ListBox1.Items.Clear();
//no need not to write tostring() to a string fname,lname or mname
listBox1.Items.Add(fname.ToString() + lname.ToString());
listBox1.Items.Add(faname.ToString());
listBox1.Items.Add(mname.ToString());
string value="";
if(radioButton1.Checked)
{
//value = radioButton1.Text;
//listBox1.Items.Add(value);
listBox1.Items.Add(radioButton1.Text);
}
else if(radioButton2.Checked)
{
//value = radioButton2.Text;
listBox1.Items.Add(radioButton2.Text);
}
string skil="";
if (checkBox1.Checked)
{
//skil = checkBox1.Text;
listBox1.Items.Add(checkBox1.Text);
}
else if(checkBox2.Checked)
{
//skil = checkBox2.Text;
listBox1.Items.Add(checkBox2.Text);
}
else if(checkBox3.Checked)
{
//skil = textBox5.Text;
listBox1.Items.Add(textBox5.Text);

}
}&lt;/pre&gt;</pre>
