OleDbException當調用OleDbConnection打開方法

我想操縱我的asp網絡mvc應用程序中的Excel 2010文件。OleDbException當調用OleDbConnection打開方法

這是代碼：

string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\teste.xlsx;Extended Properties=\"Excel 12.0 Xml;HDR=YES\";"; 
OleDbConnection conexao = new OleDbConnection(connectionString); 
conexao.Open();

Open（）方法trows例外，我無法找出原因。

例外：

Erro: System.Data.OleDb.OleDbException (0x80004005): Failure creating file. 
    at System.Data.OleDb.OleDbConnectionInternal..ctor(OleDbConnectionString constr, OleDbConnection connection) 
    at System.Data.OleDb.OleDbConnectionFactory.CreateConnection(DbConnectionOptions options, DbConnectionPoolKey poolKey, Object poolGroupProviderInfo, DbConnectionPool pool, DbConnection owningObject) 
    at System.Data.ProviderBase.DbConnectionFactory.CreateConnection(DbConnectionOptions options, DbConnectionPoolKey poolKey, Object poolGroupProviderInfo, DbConnectionPool pool, DbConnection owningConnection, DbConnectionOptions userOptions)

    at System.Data.ProviderBase.DbConnectionInternal.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory) 
    at System.Data.OleDb.OleDbConnection.Open()

是的文件在您訪問它的同時打開？ –

使用來回文件路徑的變量與逐字字符串：

string path = @"c:\teste.xlsx"; 
string connectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=\"Excel 12.0 Xml;HDR=YES\";");", path);

否則，你需要屏蔽反斜線像"c:\\teste.xlsx"：
