问题描述
我试图创造一个VB.Net类型大小的参数数组:
I'm trying to create a typed-sized parameters array in VB.Net:
Dim parameters() As SqlParameter = New SqlParameter() _
{
New SqlParameter("@first_name", SqlDbType.VarChar, 50) {Value = "john"},
New SqlParameter("@last_name", SqlDbType.VarChar, 50) {Value = "doe"},
New SqlParameter("@age", SqlDbType.Int) {Value = 18},
New SqlParameter("@id", SqlDbType.Int) {Value = 123}
}
不过VS说:值'未声明。它可能无法访问由于其保护级别
But VS says: Value' is not declared. It may be inaccessible due to its protection level
什么是错的code以上?
What's wrong with the code above?
谢谢!
推荐答案
您需要使用VB语法对象初始化:
You need to use the VB syntax for object initializers:
Dim parameters() As SqlParameter = New SqlParameter() _
{
New SqlParameter("@first_name", SqlDbType.VarChar, 50) With { .Value = "john"},
New SqlParameter("@last_name", SqlDbType.VarChar, 50) With { .Value = "doe"},
New SqlParameter("@age", SqlDbType.Int) With { .Value = 18},
New SqlParameter("@id", SqlDbType.Int) With { .Value = 123}
}
