Question

我正在使用以下代码进行Excel上传

 OleDbConnection sSourceConnection;
            string properties = "Excel 8.0; HDR=NO; IMEX=1;";//properties set for connection to excel
            string sSourceConstr = @"Provider=Microsoft.ACE.OLEDB.12.0; Data Source=" + filePath + ";Extended Properties=\"" + properties + "\"";
            sSourceConnection = new OleDbConnection(sSourceConstr);//creating the OLEDB connection
            try
            {
                //select statement to select data from the first excel sheet
                string sql = string.Format("Select * FROM [{0}]", "Sheet1$");

                //commands to fill the dataset with excel data
                OleDbDataAdapter excelAdapter = new OleDbDataAdapter();
                OleDbCommand command = new OleDbCommand(sql, sSourceConnection);
                sSourceConnection.Open();
                excelAdapter.SelectCommand = command;
                excelAdapter.Fill(dSet, EXCEL_DATA);

我必须上传大约300条记录。一栏有一些文字评论。评论的长度从10个字符到1000个字符不等。但是所有高于255长度的评论都会在该列中被截断。

我已使用此帖子Excel cell-values are truncated by OLEDB-provider来更改注册表设置，但它无效。

我也尝试了帖子OleDB & mixed Excel datatypes : missing data中提到的所有内容，但仍然无效。

Answer 1

我使用的是ACE引擎，所以更新注册表的正确位置是

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\14.0\Access Connectivity Engine\Engines\Excel\TypeGuessRowsHKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\14.0\Access Connectivity Engine\Engines\Excel\TypeGuessRows

Answer 2

对于Microsoft Office 2010-2013-2016 / 365

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\14.0\Access Connectivity Engine\Engines\Excel

最好是扫描文本'TypeGuessRows'，当你找到它时，结合Excel，将其值设置为0.我们在这个位置找到了另一个重要的位置

\HKEY_LOCAL_MACHINE \SOFTWARE\Microsoft\Office \ClickToRun\REGISTRY \MACHINE\Software \Wow6432Node \Microsoft \Office\16.0\Access Connectivity Engine\Engines\Excel.

在Excel上传时，单元格值会被截断
