[Solved] ASP.Net Error: Implicit conversion from data type nvarchar to varbinary(max) is not allowed. Use the CONVERT function to run this query

Hi developers,

When i am tried to insert base64 string to database i got the following error

"Implicit conversion from data type nvarchar to varbinary(max) is not allowed. Use the CONVERT function to run this query."

My base64 string: iVBORw0KGgoAAAANSUhE....

My database query:

Table : 

CREATE TABLE [dbo].[Mas_CustomerKYCImageDetails](
	[IDProofImageName] [varchar](2000) NULL,
	[IDProofImageData] varbinary(max)
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

Stored procedure 

CREATE Proc [dbo].[Cli_Ins_CustomerKYCImageDetails]
(
    @IDProofImageName varchar(2000),
    @IDProofImageData varbinary(max)
)
as
Begin

    Insert into Mas_CustomerKYCImageDetails
(
    IDProofImageName,
    IDProofImageData
) values
(
    @IDProofImageName,
    CONVERT(varbinary(MAX), @IDProofImageData)
)

If anyone know how to resolve this error, kindly suggest me 

Thanks and Regards,
