如何将所有行转换为 txt 文件？

Question

我已经有了从 .xls 到 .txt 的转换代码。但问题是，它只导出一行并停止。我需要添加什么代码才能读取所有行并将其转换为 txt 文件？

下面是我的代码：

using (OleDbConnection cn = new OleDbConnection())
        {
            using (OleDbCommand cmd = new OleDbCommand())
            {
                cn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + @"C:\Users\jediablaza\Documents\EDIExcel\EDIExcel.xls" + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=1\";";
                cmd.Connection = cn;
                cmd.CommandText = "SELECT * from [Sheet1$]";
                using (OleDbDataAdapter adp = new OleDbDataAdapter(cmd))
                {
                    DataTable dt = new DataTable();
                    adp.Fill(dt);
                    using (StreamWriter wr = new StreamWriter(@"C:\Users\jediablaza\Documents\EDIExcel\EDIExcel.txt"))
                    {
                        foreach (DataRow row in dt.Rows)
                        {

                                wr.WriteLine(row[0] + "\t" + row[1] + "\t" + row[2] + "\t" + row[3] + "\t" + row[4]);

                        }
                    }
                }
            }
        }

文本的输出如下所示

SHARPDTL    TESTDTL1    TESTDTL2    TESTDTL3    TESTDTL4

但是excel文件内容是

SHARPHDR1   TESTDHR1    TESTHDR2    TESTHDR3    TESTHDR4
SHARPDTL    TESTDTL1    TESTDTL2    TESTDTL3    TESTDTL4

Answer 1

我认为问题出在您的连接上属性：HDR=Yes。

所以第一行是文件的header。将其更改为 HDR=No

"HDR=Yes;" indicates that the first row contains columnnames, not data. "HDR=No;" indicates the opposite.

参考link：excel connection

显然你的问题是你在 foreach 循环中使用了固定索引。

我试图在下一个块中修复你的代码，我不能保证它会运行因为它是在我的手机上制作的，仅供参考。

using (OleDbConnection cn = new OleDbConnection())
    {
        using (OleDbCommand cmd = new OleDbCommand())
        {
            cn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + @"C:\Users\jediablaza\Documents\EDIExcel\EDIExcel.xls" + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=1\";";
            cmd.Connection = cn;
            cmd.CommandText = "SELECT * from [Sheet1$]";
            using (OleDbDataAdapter adp = new OleDbDataAdapter(cmd))
            {
                DataTable dt = new DataTable();
                adp.Fill(dt);
                using (StreamWriter wr = new StreamWriter(@"C:\Users\jediablaza\Documents\EDIExcel\EDIExcel.txt"))
                {
                    foreach (DataRow row in dt.Rows)
                    {
                            var strBldr = new StringBuilder();

                            foreach (var col in row.Columns)
                            {
                                strBldr.Append("{col}\t");
                            }

                            wr.WriteLine(strBldr);
                    }
                }
            }
        }
    }
