急的哈!!!!!!1
public DataTable Load(string connStr,int ClassID,int maxCount,int Abc)
{
//??????
SqlConnection cnn;
SqlCommand cmd;
SqlDataAdapter dap;
DataSet dst;
//?????
cnn = new SqlConnection(connStr);
dst = new DataSet();
if (ClassID==0)
{
if (maxCount==0)
{
cmd = new SqlCommand("select ID,classID," + Convert.ToString("Title").Substring(1, Abc) + ",UpdateTime from News order by UpdateTime desc ", cnn);
}
else
{
cmd = new SqlCommand("select top " + maxCount.ToString() + " * from News ",cnn);
}
}
else
{
if (maxCount==0)
{
cmd = new SqlCommand("select * from News where [ClassID]=" + ClassID.ToString() + "",cnn);
}
else
{
cmd = new SqlCommand("select top " + maxCount.ToString() + " * from News where [ClassID]=" + ClassID.ToString() + "",cnn);
}
}
dap = new SqlDataAdapter(cmd);
dap.Fill(dst,"News");
cnn.Close(); //?????
//????
return dst.Tables["News"];
}
我是一个初学者,请问各位这是怎么回事情出现错 “Load”方法没有采用“4”个参数的重载
