下方代码是打开文件和保存文件到txt中
private void btnopen_click(object sender,eventargs e) //点击打开按钮
{
if (this.openfiledialog.showdialog() == dialogresult.ok) //打开对话框后判断是否点击确定了
{
string filename =this.openfiledialog1.filename;
system.io.streamreader reader = new system.io.stream.streamreader(filename,encoding.default);
this.txtcontent.text =reader.readtoend();//将读取到的内容写到文本框中
reader.close(); //结束
}
}
private void btnsave_click(object sender,eventargs e)
{
if(this.saefiledialog1.showdialog() == dialogresult.ok)
{
string filename =this.savefiledialog1.filename;
system.io.streamwriter sriter =new system.io.streamwriter (filename,encoding.deafult);
writer.write (this.txtcontent.text);//将文本框中的内容写到目标文件中
writer.flush.();//不懂
writer.close();//结束
}
}
}
}
