Question

任何帮助我在这里做错了什么？如果我试图将示例TestCaseName的唯一行读取到case_1，那么我将获取不同行的数据。

如何确保其仅读取要求阅读的内容？我正在使用where子句，但似乎没有过滤它。

string connectionString = String.Format(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=""Excel 8.0;HDR=YES;IMEX=1;""", EXCELFILENAME);

string testCaseName = "case_1
string query = String.Format("SELECT * from [{0}$] WHERE TestCaseName=\"{1}\"", workbookName, testCaseName);

OleDbDataAdapter dataAdapter = new OleDbDataAdapter(query, connectionString);

DataSet dataSet = new DataSet();
dataAdapter.Fill(dataSet);  
DataTable myTable = dataSet.Tables[0]; 

TestCaseName       Name    Active   Status  etc...
----------------------------------------------------------------
case_1             Tom     yes      Completed   etc...
----------------------------------------------------------------
case_2             John    yes                  etc...
----------------------------------------------------------------
case_3             Jim     yes                  etc...
----------------------------------------------------------------
case_4             Don     yes                  etc...
----------------------------------------------------------------
case_5             Sam     yes      Visitor     etc...
----------------------------------------------------------------

这是我测试过的代码。它似乎工作得很好。如果您没有，那么我只能假设您的电子表格与我的结构不完全相同。

string connectionString = "Provider=Microsoft.Ace.OLEDB.12.0;Data Source=" + filename + ";Extended Properties=\"Excel 8.0;HDR=YES;IMEX=1\"";
string testCaseName = "case_1";
string query = "SELECT * from [Sheet1$] WHERE TestCaseName=\"" + testCaseName + "\"";
DataTable dt = new DataTable();

using (OleDbConnection conn = new OleDbConnection(connectionString))
{
    conn.Open();

    using (OleDbDataAdapter dataAdapter = new OleDbDataAdapter(query, conn))
    {
        DataSet ds = new DataSet();
        dataAdapter.Fill(ds);
        dt = ds.Tables[0];
    }

    conn.Close();
}

使用OleDb数据检索读取Excel ROW
