Calling a Stored Procedure using C# with XML Datatype
- by Lakeshore
I am simply trying to call a store procedure (SQL Server 2008) using C# and passing XMLDocument to a store procedure parameter that takes a SqlDbType.Xml data type. I am getting error: Failed to convert parameter value from a XmlDocument to a String. Below is code sample. How do you pass an XML Document to a store procedure that is expecting an XML datatype? Thanks.
XmlDocument doc = new XmlDocument();
//Load the the document with the last book node.
XmlTextReader reader = new XmlTextReader(@"C:\temp\" + uploadFileName);
reader.Read();
// load reader
doc.Load(reader);
connection.Open();
SqlCommand cmd = new SqlCommand("UploadXMLDoc", connection);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@Year", SqlDbType.Int);
cmd.Parameters["@Year"].Value = iYear;
cmd.Parameters.Add("@Quarter", SqlDbType.Int);
cmd.Parameters["@Quarter"].Value = iQuarter;
cmd.Parameters.Add("@CompanyID", SqlDbType.Int);
cmd.Parameters["@CompanyID"].Value = iOrganizationID;
cmd.Parameters.Add("@FileType", SqlDbType.VarChar);
cmd.Parameters["@FileType"].Value = "Replace";
cmd.Parameters.Add("@FileContent", SqlDbType.Xml);
cmd.Parameters["@FileContent"].Value = doc;
cmd.Parameters.Add("@FileName", SqlDbType.VarChar);
cmd.Parameters["@FileName"].Value = uploadFileName;
cmd.Parameters.Add("@Description", SqlDbType.VarChar);
cmd.Parameters["@Description"].Value = lblDocDesc.Text;
cmd.Parameters.Add("@Success", SqlDbType.Bit);
cmd.Parameters["@Success"].Value = false;
cmd.Parameters.Add("@AddBy", SqlDbType.VarChar);
cmd.Parameters["@AddBy"].Value = Page.User.Identity.Name;
cmd.ExecuteNonQuery();
connection.Close();
