从文本框中的两行列表框中添加相同的字符串？

Question

是否可以在列表框的两行中添加texte中输入的相同字符串，如下图所示？

private void metroButton10_Click(object sender, EventArgs e)
    {
        listBox2.Items.Add("Next station: " + metroTextBox1.Text);
        listBox2.Items.Add(Environment.NewLine)
        metroTextBox1.Clear();
        listBox2.SelectedIndex = 0;
    }

Answer 1

使用以下代码。

 private void button1_Click(object sender, EventArgs e)
    {
        listBox1.Items.Add("Next Station: "+textBox1.Text);
        listBox1.Items.Add("Station: " + textBox1.Text);
    }

你不能使用新行。因为列表框可以在一行中包含一个项目。

Answer 2

当然，您可以在列表框的两行中的文本框中添加相同的字符串;

#include<windows.h>
#include<glut.h>

GLfloat x1=100.0f;
GLfloat y1=150.0f;
GLsizei rsize = 50;

GLfloat xstep=1.0f;
GLfloat ystep=1.0f;

GLfloat windowWidth;
GLfloat windowHeight;


void scene(void){
   glClear(GL_COLOR_BUFFER_BIT);
   glColor3f(1.0f,0.0f,0.0f);

   glRectf(x1,y1,x1+rsize,y1-rsize);

   glutSwapBuffers();
}

void setupRc(void){

  glClearColor(0.0f,0.0f,1.0f,0.0f);

}

void changeSize(GLsizei w,GLsizei h){
  if(h==0)
  h=1;
  glViewport(0,0,w,h);
  glMatrixMode(GL_PROJECTION);
  glLoadIdentity();
   if(w>=h){
     windowWidth=250.0f*w/h;
     windowHeight=250.f;
   }
   else{
     windowWidth=250.0f;
     windowHeight=250.f*h/w;
   } 

   glOrtho(0.0f,windowWidth,0.0f,windowHeight,1.0f,-1.0f);


   glMatrixMode(GL_MODELVIEW);
   glLoadIdentity();


}




void main(void){

   glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGBA);

   glutCreateWindow("Rectangle");

   glutReshapeFunc(changeSize);
   glutDisplayFunc(scene);
   setupRc();

   glutMainLoop();

}
