c# 为何通过短息猫接受不了短信内容
private void button1_Click(object sender, EventArgs e)
{
//连接设备
if(GMS.GSMModemInitNew(comboBox1.Text,comboBox2.Text,null,null,false,textBox2.Text)==false)
{
MessageBox.Show("连接失败!"+GMS.GSMModemGetErrorMsg(),"提示",MessageBoxButtons.OK);
return;
}
//接受短信
string content = GMS.GSMModemSMSReadAll(0);
if (content == null)
{
this.getMessage();
return;
}
content = content.Replace("||", "|");//replace || to |
string[] str_sp = content.Split('|');//进行分离
int k = 0;
string[,] str_Sp = new string[2, str_sp.Length / 2];
for (int i = 0; i < str_sp.Length / 2; i++)
{
for (int j = 0; j < 2; j++)
{
str_Sp[j, i] = str_sp[k];
if (k % 2 != 0)
this.InsertMessage("insert into RecivedBox(Mobile,Content,reciveTime)values('"+Convert.ToString(str_Sp[0,i])+"'),'"+Convert.ToString(str_Sp[1,i])+"','"+DateTime.Now.ToString()+"')");
k++;
}
}
this.getMessage();
}
