如何使用保存文件对话框保存bvh文件？ [英] How to save bvh file using save file dialog?

问题描述

如何使用C＃中的按钮使用保存文件对话框保存此bvh文件？



我绝对是编程的初学者。它会自动保存在Bin / release文件夹中。我尝试了很多方法，但我没有找到结果。有人可以帮忙吗？



我尝试了什么：



{

if（BVHFile == null&& sensor！= null）

{





DateTime thisDay = DateTime.Now;

string txtFileName = thisDay.ToString（dd.MM.yyyy_HH.mm）;

BVHFile = new writeBVH （txtFileName）;

}

}

How can I save this bvh file using save file dialog with button in C#?

And I am absolutely beginner for programming. It is saving automatically in Bin/release folder. I tried a lot ways but I didn't find results. Could anyone help?

What I have tried:

{
if (BVHFile == null && sensor != null)
{


DateTime thisDay = DateTime.Now;
string txtFileName = thisDay.ToString("dd.MM.yyyy_HH.mm");
BVHFile = new writeBVH(txtFileName);
}
}

private void button2_Click(object sender, System.EventArgs e)  
{  
   // Displays a SaveFileDialog so the user can save the Image  
   // assigned to Button2.  
   SaveFileDialog saveFileDialog1 = new SaveFileDialog();  
   saveFileDialog1.Filter = "JPeg Image|*.jpg|Bitmap Image|*.bmp|Gif Image|*.gif";  
   saveFileDialog1.Title = "Save an Image File";  
   saveFileDialog1.ShowDialog();  

   // If the file name is not an empty string open it for saving.  
   if(saveFileDialog1.FileName != "")  
   {  
      // Saves the Image via a FileStream created by the OpenFile method.  
      System.IO.FileStream fs =   
         (System.IO.FileStream)saveFileDialog1.OpenFile();  
      // Saves the Image in the appropriate ImageFormat based upon the  
      // File type selected in the dialog box.  
      // NOTE that the FilterIndex property is one-based.  
      switch(saveFileDialog1.FilterIndex)  
      {  
         case 1 :   
         this.button2.Image.Save(fs,   
            System.Drawing.Imaging.ImageFormat.Jpeg);  
         break;  

         case 2 :   
         this.button2.Image.Save(fs,   
            System.Drawing.Imaging.ImageFormat.Bmp);  
         break;  

         case 3 :   
         this.button2.Image.Save(fs,   
            System.Drawing.Imaging.ImageFormat.Gif);  
         break;  
      }  

   fs.Close();  
   }
