示例

下面的示例演示如何设置 Password。

using System;
using System.Data.SqlClient;

class Program {
   public static void Main() {
      SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder();

      builder["Password"] = null;
      string aa = builder.Password;
      Console.WriteLine(aa.Length);

      builder["Password"] = "??????";
      aa = builder.Password;
      Console.WriteLine(aa.Length);

      try {
         builder.Password = null;
      }
      catch (ArgumentNullException e) {
         Console.WriteLine("{0}", e);
      }
   }
}

Imports System.Data.SqlClient
Public Class Program
   Public Shared Sub Main()

      Dim builder As New SqlConnectionStringBuilder()

      builder("Password") = Nothing
      Dim aa As String = builder.Password
      Console.WriteLine(aa.Length)

      builder("Password") = "??????"
      aa = builder.Password
      Console.WriteLine(aa.Length)

      Try
         builder.Password = Nothing
      Catch e As ArgumentNullException
         Console.WriteLine("{0}", e)
      End Try
   End Sub
End Class

注解

此属性对应于连接字符串中的“Password”和“pwd”键。

如果未 Password 设置该值并检索该值，则返回值为 Empty。 若要重置连接字符串的密码，请将 null 传递给 Item 属性。
