求这段代码的意思
--------------------编程问答-------------------- 执行更新或者删除的SQL语句 --------------------编程问答-------------------- 有点不对吧，返回值是int型的，而sc.ExecuteNonQuery()并不返回任何值啊……
public int ExecSQL(global::System.Object tableAdapter,
global::System.String strSQL)
{
try
{
Type tpAdapter = tableAdapter.GetType();
tpAdapter.InvokeMember("Connection",
BindingFlags.SetProperty |
BindingFlags.Public |
BindingFlags.NonPublic |
BindingFlags.Instance,
null, tableAdapter, new global::System.Object[] { this._connection });
global::System.Data.SqlClient.SqlCommand[] sCommCollection =
(global::System.Data.SqlClient.SqlCommand[])tpAdapter.InvokeMember("CommandCollection",
BindingFlags.GetProperty |
BindingFlags.Public |
BindingFlags.NonPublic |
BindingFlags.Instance,
null, tableAdapter, null);
global::System.Data.SqlClient.SqlCommand sc = sCommCollection[0].Clone();
sc.CommandText = strSQL;
sc.Connection.Open();
return sc.ExecuteNonQuery();
}
catch (Exception ex)
{
throw ex;
}
}
--------------------编程问答-------------------- sc.ExecuteNonQuery() 方法的返回值是个int,为操作影响的行数 --------------------编程问答-------------------- Exec SQL
补充：.NET技术 , ASP.NET
