Microsoft.ACE.OLEDB.12.0 CSV ConnectionString [英] Microsoft.ACE.OLEDB.12.0 CSV ConnectionString

问题描述

我知道这个问题不时被问，但我找不到任何满意的解决方案。

I know questions this kind are asked from time to time but i can't find any satisfying solution.

如何使用MS ACE OLEDB 12打开CSV文件？
我尝试下面的代码。

How can I open a CSV-File using MS ACE OLEDB 12? I try it with the following code.

DbConnection connection = new OleDbConnection();
connection.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\Documents;Extended Properties=\"Text;HDR=Yes\"";
connection.Open();
DbCommand cmd;

cmd = connection.CreateCommand();
cmd.CommandText = "SELECT * FROM [Mappe1#csv]";
DbDataReader reader = cmd.ExecuteReader();

while (reader.Read())
{
    for (int i = 0; i < reader.FieldCount; i++)
        Console.Write("(" + reader.GetValue(i).ToString() + ")");

    Console.WriteLine();
}

cmd.Dispose();
connection.Dispose();
Console.WriteLine("Done");
Console.ReadKey();

问题是只找到一列。文本由;分隔。即使当我指定分隔符与Delimited（|）f.e。

The Problem is that only one column is found. The Text is delimited by ';'. Even when i specifiy the delimiter with "Delimited(|)" f.e. it will not work.

我找不到此提供程序的任何文档...

I can't find any documentation for this provider...

This helped me getting a semicolon-delimited csv to parse in C# using ACE.OLEDB.12.0: http://sqlserverpedia.com/blog/sql-server-bloggers/use-ace-drivers-and-powershell-to-talk-to-text-files/:

创建 schema.ini 文本文件在与要导入的csv文件相同的目录中，使用以下内容：

Create a schema.ini text file in the same directory as the csv file you want to import with the following contents:

[fileIwantToImport.csv]
Format=Delimited(;)
ColNameHeader=True

但是太好了。

看起来像连接字符串中的 FORMAT = Delimited（;） ...

Seems like the FORMAT=Delimited(;) in the connection string has gone out of fashion...
