在平面文件连接器上设置行分隔符属性

Question

我正在创建一个BIML脚本，允许我导入CSV。

但是，平面文件连接管理器上的属性Row Delimiter以某种方式设置为Vertical Bar，就像列分隔符一样。这会阻止我导入文件。

将列分隔符设置为竖线，我就是不明白为什么它还将行分隔符设置为竖线…

每当我手动将行分隔符设置为CRLF时，它就会像符咒一样工作。但在BIML中，它始终设置为与列分隔符相同的值。

我找不到发生这种情况的地方...

我尝试以多种方式使用表达式来设置行分隔符，但可惜.

有谁有什么线索吗？

Answer 1

找到了

                if (columnCount == myColumns.Length)
                {
                    columnDelimiter = "CRLF";
                }
                {
                    columnDelimiter = "|";
                }

你那里缺少一个else。它应该是

                if (columnCount == myColumns.Length)
                {
                    columnDelimiter = "CRLF";
                }
                else
                {
                    columnDelimiter = "|";
                }
