The data types text and nvarchar are incompatible in the equal to operator

Question

this is my code

ProductController.cs

public ActionResult Details(string id)
{
    product productx = productDB.products.Single(pr =&         


        

Answer 1

This problem can to occur then use:

Exemple

string sql = "Select * from TB_USER where Name = @Name";
SqlCommand cmd = new SqlCommand(sql);

This is incompatible:

cmd.Parameters.Add("@Nome", SqlDbType.Text).Value = nome;

Change for:

cmd.Parameters.Add("@Nome", SqlDbType.VarChar, 50).Value = nome;
