完全按你的要求写的,供参考:前提是码整码带XML文件已创建好,在窗体里选择该XML文件,数据再行操作:
窗体:
//选择XML按钮private void btnXML_Click(object sender,整站源站源傻瓜交易指标源码6 EventArgs e)
{
DataTable dt = new DataTable();
OpenFileDialog xmlFile = new OpenFileDialog();
xmlFile.Filter = "*.xml|";
xmlFile.Title = "请选择xml文件";
if (xmlFile.ShowDialog() == DialogResult.OK)
{
this.txtPath.Text = xmlFile.FileName;//在textBox1控件中显示选择的路径
dt=GetXML(this.txtPath.Text);
}
if(!dt.Equals(null)&&dt.Rows.Count>0)
LoadData(dt, dgvXML);//加载到窗体中
}
//保存按钮
private void button1_Click(object sender, EventArgs e)

int n = SaveDgv();
if (n > 0)

MessageBox.Show("保存成功!");
DataTable dt = new DataTable();
dt = GetXML(this.txtPath.Text);

}
else

声音数字化的过程分为哪三个步骤
1、引言
就音频而言,整站源站源美国溯源码无论是码整码带算法多样性,Codec种类还是数据音频编解码复杂程度都远远比视频要高。视频的link实时源码Codec目前还主要是以宏块为处理单元,预测加变换的混合编码框架,例如H.和H.都是在这一框架下。而音频则相当复杂,项城源码建站且不同的场景必须要选择不同的音频编解码器。以下就是本次为大家分享的主要内容,希望通过此次分享可以使大家对音频编解码有一个整体的认识,并在实际应用中有参考的依据。
本次分享的内容提纲:
1)语音/音频编码总表;
2)数字语音基本要素;
3)为什么要压缩;
4)编码器考虑的因素;
5)语音经典编码模型;
6)ISO;
7)编码模型;
8)USAC;
9)编码;
)使用选型考虑的因素。
