在这里,我想使用C#代码将我的Excel工作表中的所有数据插入SQL Server
表
我的Excel表格包含这样的数据
ID Name Designation ProfilePicture
--------------------------------------------
1 ABC Manager C:\Pictures\1.jpg
2 DEF Asst.Manager C:\Pictures\2.jpg
我有将数据插入表中的代码
String filePath = filePathText.Text;
String fileExtension = "Excel 12.0";
if (filePath != null)
{
String xlsConnection = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + filePath + ";Extended Properties=" + "\"" + fileExtension + ";HDR=YES;\"";
String sqlConnection = "Your Connection String";
//Connection to Excel work book
OleDbConnection xlsConnectionString = new OleDbConnection(xlsConnection);
//Fetch data from Excel
OleDbCommand cmd = new OleDbCommand("Select [ID],[Name],[Designation],[ProfilePicture] from [Sheet1$]", xlsConnectionString);
xlsConnectionString.Open();
OleDbDataReader dReader;
dReader = cmd.ExecuteReader();
SqlBulkCopy sqlBulk = new SqlBulkCopy(sqlConnection);
//Destination table name
sqlBulk.DestinationTableName = "EXCEL_DATA";
sqlBulk.WriteToServer(dReader);
xlsConnectionString.Close();
}
如果单击按钮,则会运行此段代码。
我的问题是,如何从Excel工作表上传图片(工作表具有图像的路径)。到SQL Server
表。我想通过使用Excel工作表中提供的Imagepath来获取图片,并将其存储为varbinary(MAX)
中的SQL Server
。
答案 0 :(得分:2)
感谢那些真正努力发布答案的人。最后我自己解决了这个问题。
以下代码有助于使用SQL Server
中提供的路径将图像插入Excel sheet
。
private void insert_Click(object sender, EventArgs e)
{
UInt64 ID = 0;
String Name = String.Empty;
String Designation = String.Empty;
String ProfilePicture = String.Empty;
String filePath = filePathText.Text;
Excel.Application xlApp = null;
Excel.Workbook xlWorkbook = null;
Excel._Worksheet xlWorksheet = null;
Excel.Range xlRange = null;
String sqlConnectionString = "Your Connection String goes here";
String insertRecord = "INSERT_USER_RECORDS";
SqlConnection sqlConnection = new SqlConnection(sqlConnectionString);
SqlCommand sqlCommand = new SqlCommand(insertRecord, sqlConnection);
sqlCommand.CommandType = CommandType.StoredProcedure;
sqlConnection.Open();
if (filePath != null)
{
try
{
xlApp = new Excel.Application();
xlWorkbook = xlApp.Workbooks.Open(filePath);
xlWorksheet = (Excel._Worksheet)xlWorkbook.Sheets[1];
xlRange = xlWorksheet.UsedRange;
int rowCount = xlRange.Rows.Count;
int colCount = xlRange.Columns.Count;
for (int row = 1; row <= rowCount; row++)
{
for (int col = 1; col <= colCount; col++)
{
MessageBox.Show((xlRange.Cells[row, col] as Microsoft.Office.Interop.Excel.Range).Value2.ToString());
// Check xlRange for Every run. And assign values to local variables. Here I just show the values using MsgBox
// If you get the Path of Image then call the function to Convert Image into byte
// Convert Image to Byte Function definition.
/* System.IO.FileStream fs = new System.IO.FileStream(ProfilePicture, System.IO.FileMode.Open);
Byte[] imageAsBytes = new Byte[fs.Length];
fs.Read(imageAsBytes, 0, imageAsBytes.Length);
fs.Close();
return imageAsBytes; */
}
sqlCommand.Parameters.Clear();
sqlCommand.Parameters.Add("@Name", SqlDbType.NVarChar).Value = FirstName;
sqlCommand.Parameters.Add("@Designation", SqlDbType.NVarChar).Value = LastName;
sqlCommand.Parameters.Add("@ProfilePicture", SqlDbType.VarBinary).Value = imageAsBytes;
sqlCommand.Parameters.Add("@ID", SqlDbType.BigInt).Value = ID;
sqlCommand.ExecuteNonQuery();
}
MessageBox.Show(Path.GetFileName(filePath) + "is Successfully imported to SQL Server", "Result", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "Exception", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
finally
{
//Release All objects and close the Connection to prevent the Excel file from lock.
sqlConnection.Close();
GC.Collect();
GC.WaitForPendingFinalizers();
Marshal.FinalReleaseComObject(xlRange);
Marshal.FinalReleaseComObject(xlWorksheet);
xlWorkbook.Close(Type.Missing, Type.Missing, Type.Missing);
Marshal.FinalReleaseComObject(xlWorkbook);
xlApp.Quit();
Marshal.FinalReleaseComObject(xlApp);
}
}
else
{
MessageBox.Show("Please Select the Valid file to import");
}
}
此代码工作正常,可帮助我将图像从SQL
插入Excel
数据库。
无论excel文件的版本如何。
