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scala 源码解读 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);
LoadData(dt,码整码带 dgvXML);//刷新加载
}
else
{
MessageBox.Show("保存失败!");
DataTable dt = new DataTable();
dt = GetXML(this.txtPath.Text);
LoadData(dt,数据优化版wr指标源码 dgvXML);//刷新加载
}
}
//删除按钮
private void btnDelete_Click(object sender, EventArgs e)
{
int n = 0;//判断是否删除
for (int i = 0; i < dgvXML.SelectedRows.Count; i++)

声音数字化的过程分为哪三个步骤
1、引言
就音频而言,整站源站源库存管理手机版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。视频的快递计算运费网站源码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,操盘密码主力监控源码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。
