如何使用Excel列创建SQL表？

我需要帮助从Excel自动生成列名。我认为：我们可以做以下代码：如何使用Excel列创建SQL表？

CREATE TABLE [dbo].[Addresses_Temp] ( 
    [FirstName] VARCHAR(20), 
    [LastName] VARCHAR(20), 
    [Address]  VARCHAR(50), 
    [City]  VARCHAR(30), 
    [State]  VARCHAR(2), 
    [ZIP]   VARCHAR(10) 
)

via C＃。我如何从Excel学习列名？

private void Form1_Load(object sender, EventArgs e) 
{ 
    ExcelToSql(); 
} 

void ExcelToSql() 
{ 
    string connectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Source\MPD.xlsm;Extended Properties=""Excel 12.0;HDR=YES;"""; 
    // if you don't want to show the header row (first row)    
    // use 'HDR=NO' in the string    
    string strSQL = "SELECT * FROM [Sheet1$]";    
    OleDbConnection excelConnection = new OleDbConnection(connectionString);   
    excelConnection.Open(); // This code will open excel file.    
    OleDbCommand dbCommand = new OleDbCommand(strSQL, excelConnection);   
    OleDbDataAdapter dataAdapter = new OleDbDataAdapter(dbCommand);    

    // create data table    
    DataTable dTable = new DataTable();    
    dataAdapter.Fill(dTable);    

    // bind the datasource   
    // dataBingingSrc.DataSource = dTable;   
    // assign the dataBindingSrc to the DataGridView   
    // dgvExcelList.DataSource = dataBingingSrc;    // dispose used objects   
    if (dTable.Rows.Count > 0) 
     MessageBox.Show("Count:" + dTable.Rows.Count.ToString()); 
    dTable.Dispose();   
    dataAdapter.Dispose();   
    dbCommand.Dispose();    
    excelConnection.Close();   
    excelConnection.Dispose(); 
}

您应该可以迭代DataTable的列集合以获取列名称。

System.Data.DataTable dt; 
dt = new System.Data.DataTable(); 
foreach(System.Data.DataColumn col in dt.Columns) 
{ 
    System.Diagnostics.Debug.WriteLine(col.ColumnName); 
}
