"System.AccessViolationException: Attempted to read or write protected memory" While Filling a DataTable
提问by George Filippakos
Using ASP.NET 4.51 and VS 2013 I am getting the following error when attempting to Fill a datatable using a stored procedure.
使用 ASP.NET 4.51 和 VS 2013 尝试使用存储过程填充数据表时出现以下错误。
System.AccessViolationException: Attempted to read or write protected memory
I have have traced the error to the following:
我已将错误追溯到以下几点：
Using myDT As New DAL.mbr_MediaComments.usrsp_mbr_MediaComments_CommentorsDataTable
Using myTA As New DAL.mbr_MediaCommentsTableAdapters.usrsp_mbr_MediaComments_CommentorsTableAdapter
myTA.Fill(myDT, toMbrID, mediaID) <------System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
Here is my stored procedure definition:
这是我的存储过程定义：
CREATE PROCEDURE [dbo].[usrsp_mbr_MediaComments_Commentors]
-- Add the parameters for the stored procedure here
@mbrID int = 0,
@mediaID bigint = 0
AS
BEGIN
//my query code
END

I found the problem, the error was caused by the following:
我找到了问题，错误是由以下原因引起的：
The stored procedure had defined one of the parameters as bigint
存储过程已将参数之一定义为bigint
It should have been intas was defined in the database table schema.
它应该是在数据库表模式中定义的int。
I seems that passing an Integer value to a table adapter Stored Procedure expecting a Bigint causes an AccessViolationException error.
我似乎将整数值传递给需要 Bigint 的表适配器存储过程会导致 AccessViolationException 错误。
I hope this information helps somebody else.
我希望这些信息对其他人有帮助。
