mail merge with dynamic file path - asp.net

Question

I had a problem generating a word template because I wanted it to be selected dynamically with ddlTemplate when selected to write in it with the merge field in the word template.
this is my code:
public partial class unTemplate : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)// call the method for ONLY first time for visitor
{
{
populateDdlInstitution();
}
}
}
protected void populateDdlInstitution()
{
CRUD myCrud = new CRUD();
string mySql = #"select institutionid, institution from institution";
SqlDataReader dr = myCrud.getDrPassSql(mySql);
ddlInstitution.DataTextField = "institution";
ddlInstitution.DataValueField = "institutionid";
ddlInstitution.DataSource = dr;
ddlInstitution.DataBind();
}
protected void ddlInstitution_SelectedIndexChanged(object sender, EventArgs e)
{
// call a method to populate the template ddl
populateDdlTemplate();
}
protected void populateDdlTemplate()
{
CRUD myCrud = new CRUD();
string mySql = #"select internDocId, DocName
from internDoc
where institutionId = #institutionId";
Dictionary<string, object> myPara = new Dictionary<string, object>();
myPara.Add("#institutionId", ddlInstitution.SelectedItem.Value);
SqlDataReader dr = myCrud.getDrPassSql(mySql, myPara);
ddlTemplate.DataTextField = "DocName";
ddlTemplate.DataValueField = "internDocId";
ddlTemplate.DataSource = dr;
ddlTemplate.DataBind();
}
protected void btnSubmit_Click(object sender, EventArgs e)
{
CRUD myCrud = new CRUD();
string mySql = #"select* from intern
where institutionId = #institutionId"/*+#"select internDocId,DocName from internDoc where internDocId=internDocId"*/;
Dictionary<string, object> myPara = new Dictionary<string, object>();
myPara.Add("#institutionId", ddlInstitution.SelectedItem.Value);
//myPara.AsEnumerable(#"internDocId");
SqlDataReader dr = myCrud.getDrPassSql(mySql, myPara);
gvData.DataSource = dr;
gvData.DataBind();
}
protected void btnGenerateTemplate_Click(object sender, EventArgs e)
{
wordT();
}
private static DataTable GetRecipients()
{
//Creates new DataTable instance.
DataTable table = new DataTable();
//Loads the database.
OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + #"../../CustomerDetails.mdb");
//Opens the database connection.
conn.Open();
OleDbDataAdapter adapter = new OleDbDataAdapter("Select * from intern", conn);
//Gets the data from the database.
adapter.Fill(table);
//Releases the memory occupied by database connection.
adapter.Dispose();
conn.Close();
return table;
}
public void wordT()
{
for (int i = 0; i <= gvData.Rows.Count - 1; i++)
{
String internId = gvData.Rows[i].Cells[0].Text;
String fullName = gvData.Rows[i].Cells[7].Text;
String cell = gvData.Rows[i].Cells[8].Text;
String email = gvData.Rows[i].Cells[9].Text;
Syncfusion.DocIO.DLS.WordDocument document = new Syncfusion.DocIO.DLS.WordDocument(Server.MapPath(getPath()));
//Deleting null fields
document.MailMerge.RemoveEmptyParagraphs = true;
string[] fieldNames = new string[] { "fullName", "internId", "email", "cell" };
string[] fieldValues = new string[] { fullName, internId, email, cell };
// mail merge
document.MailMerge.Execute(fieldNames, fieldValues);
//Saves
document.Save(Server.MapPath("~/myDoc/" + email + ".docx"));
document.Close();
}
// pass message to user notifying of successfull operation
lblOutput.Text = "Word Doc output generated successfully!";
}
public string getPath()
{
DirectoryInfo di = new DirectoryInfo(#"C:\projects\unSupervisorApp\Uploads\");
foreach (var d in di.EnumerateDirectories())
{
foreach (var fi in d.EnumerateFileSystemInfos())
{
if (fi.Name == (ddlTemplate.DataTextField))
{
return fi.FullName.Replace(fi.Name, "");
}
}
}
return di.FullName;
}
}//cls
the problem:
‎1-'C:/projects/unSupervisorApp/Uploads/' is a physical path but was expected to be a virtual path.‎
2- and sometime it gives me that it i can not find the file in EnumerateDirectories.
but i get the first one the most.
getFile
getPath
path of folder + ddlselectedItem.text
