求大师!!!
Mixii 2012-04-30 05:04:33 最近做毕业设计,用动软代码生成器生成DbHelperSQL.cs文件,生成网站是成功,但是在修改的时候就出现 用户代码未处理Exception 显示throw new Exception(ex.Message);第一行:throw new Exception(ex.Message);
代码如下:
/// <summary>
/// 执行查询语句,返回DataSet
/// </summary>
/// <param name="SQLString">查询语句</param>
/// <returns>DataSet</returns>
public static DataSet Query(string SQLString)
{
using (SqlConnection connection = new SqlConnection(connectionString))
{
DataSet ds = new DataSet();
try
{
connection.Open();
SqlDataAdapter command = new SqlDataAdapter(SQLString, connection);
command.Fill(ds, "ds");
}
catch (System.Data.SqlClient.SqlException ex)
{
throw new Exception(ex.Message); //此句错误 }
return ds;
}
}
public static DataSet Query(string SQLString, int Times)
{
using (SqlConnection connection = new SqlConnection(connectionString))
{
DataSet ds = new DataSet();
try
{
connection.Open();
SqlDataAdapter command = new SqlDataAdapter(SQLString, connection);
command.SelectCommand.CommandTimeout = Times;
command.Fill(ds, "ds");
}
catch (System.Data.SqlClient.SqlException ex)
{
throw new Exception(ex.Message);
}
return ds;
}
}
