如何处理异常的“C＃”的错误，喜欢 - >

Code: 
Workbooks.Open(folderPath,filename,Excel.XlPlatform.xlWindows,"",""....)

尝试下面的代码打开Excel文件：

String connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + excelFilePath + ";Extended Properties=Excel 12.0;"; 
    // Create connection object by using the preceding connection string. 
    OleDbConnection objConn = new OleDbConnection(connString); 
    // Open connection with the database. 
    objConn.Open();
