How do I pass an array of objects to my (code behind) accessor method in ASP.Net?

Hey Guys:

Hope y'all doing well.

I've got an ASP .Net/C# question

I've got the following accessor method on my base page code behind:
-------------------------------------------------------------------
public static string RetrieveTimeStampFromAudit (AuditRecord[] auditHistory, string operationTypeStringToFind, string format)
{
//TODO Add implementation
}

I'd like to be able to call it from my ASP.Net page, more or less
in the following fashion:
-----------------------------------------------------------------
Text='<%# RetrieveTimeStampFromAudit("Foobar.AuditRecord", "Created", "MM/dd/yyyy") %>'

I'm getting casting errors at page load time.
I’ve tried changing the Method definition to
Object
Object[]

and playing with the the actual call on the Asp .Net page.

Do you have any suggestions how to manipulate this cast/definition to work?

Thanks,
JB

Hi JB, Can you post the complete code for this method : RetrieveTimeStampFromAudit()
I have a Solution for You Plz try this code :

Text='<% (string)RetrieveTimeStampFromAudit("Foobar.AuditRecord", "Created", "MM/dd/yyyy") %>'

//OR

Text='<% RetrieveTimeStampFromAudit("Foobar.AuditRecord", "Created", "MM/dd/yyyy").ToString() %>'

//OR

Text='<%# (string)RetrieveTimeStampFromAudit("Foobar.AuditRecord", "Created", "MM/dd/yyyy") %>'


//OR

Text='<%# RetrieveTimeStampFromAudit("Foobar.AuditRecord", "Created", "MM/dd/yyyy").ToString() %>'

//OR

Text='<%# RetrieveTimeStampFromAudit("Foobar.AuditRecord", "Created", "MM/dd/yyyy") as String %>'

One of the above declarations may definitely work for you.. See since the return type of this method is a string I think it would definitely be necessary to cast it to a string object.

Final Comment : Change the first parameter of the method :

public static string RetrieveTimeStampFromAudit (AuditRecord[] auditHistory, string operationTypeStringToFind, string format)
{
//TODO Add implementation
}

Open in new window

To an object of AuditRecord[] class like this one for example :

AuditRecord[] obj = new AuditRecord[10];

string test = RetrieveTimeStampFromAudit(obj,"Created","MM/dd/yyyy");

Open in new window

I think thats your issue..Its not able to cast the string "Foobar.AuditRecord" into an object of type AuditRecord[]

Also, keep in mind you are using

Text='<%# RetrieveTimeStampFromAudit("Foobar.AuditRecord", "Created", "MM/dd/yyyy") %>'

Open in new window

to call your method. Depending on where that code appears in your asp.net page, this may not work. Using the # will only work inside of a databound control, otherwise you would use

Text='<%= RetrieveTimeStampFromAudit("Foobar.AuditRecord", "Created", "MM/dd/yyyy") %>'

Open in new window

. I'm just throwing this out there, but it doesn't sound like it would produce the error you are receiving.
