当我使用Linq插入新记录时,如何获取SQL命令文本？

你需要将DataContext.Log属性设置为一个writer,你可以将一个writer包装在一个stringbuilder然后插入response.write你的stringbuilder.tostring ...

                        StringBuilder sb = new StringBuilder();
                StringWriter writer = new StringWriter(sb);
                Context.Log = writer;
                ...
                    DOINSERT & SUBMITCHANGES
                ...
                Response.Write(sb.ToString());
