Question

I have a table with the column’s datatype as xml in SQL Server 2005. I created a stored procedure to insert values into that column.

But when calling the SP from code in C#, its giving me an error

Failed to convert parameter value from a XDocument to a String.

Can anyone help with this?

This is the stored procedure I created:

Create Procedure [dbo].[TestReportRepository_Save]
@ReportExecutionTime datetime,
@ReportFile xml,

as
begin

insert into TestReportRepository(ReportExecutionTime,ReportFile) values(@ReportExecutionTime,@ReportFile)

end

The C# code is

DbParameter dbParam1 = dac.Parameter("@ReportExecutionTime", ReportExecutionTime, DbType.DateTime, ParameterDirection.Input);
DbParameter dbParam2 = dac.Parameter("@ReportFile", xmlDoc.Document, DbType.Xml, ParameterDirection.Input);

DbParameter[] dbParamColl = new DbParameter[] { dbParam1, dbParam2 };
long reportID = dac.Save("TestReportRepository_save", dbParamColl);

Please help me identify what I am doing wrong.

When passing this parameter – pass not XDocument object, but its string representation.

For XmlDocument it is XmlDocument.OuterXml, find one for XDocument and pass it
