如何为我的ID设置一个guid值，该ID是字符串类型 [英] How to set a guid value to my ID which is of string type

问题描述

当我添加一条记录时，我已经定义了Id值。但是每次它都需要默认的guid值。只有00000000-0000-0000-0000-000000000000.Hence在db中它存储两个具有相同id.again的数据当我删除添加的记录时，所有记录都被删除为id = 00000000-0000-0000-0000-000000000000，你能告诉我如何避免这个问题，以便在添加时记录它将使用一些新的guid值存储数据..

我的代码如下

Hi,
While I am adding a record I have defined the Id value.But every time it takes the default guid value..means only 00000000-0000-0000-0000-000000000000.Hence in db it store two data with same id.again when i delete the added record all the record are deleted as id=00000000-0000-0000-0000-000000000000,Can you please tell me how to avoid this prolem so that while adding a record it will store the data with some new guid values..
my codes are as follows

//Add Buttoon for adding record
    protected void btnAdd_Click(object sender, EventArgs e)
    {
        Guid id = new Guid();
        string Id = id.ToString();
        Member member = new Member();
      
        member.ID = Id;
        member.MemberID = int.Parse(txtMemberID.Text);
        member.ReceiptNo = txtReceiptNo.Text;
        member.SurName = txtSurName.Text;
        member.Name = txtName.Text;
        member.DateOfBirth = txtDateOFBirth.Text;
if (memberService.AddMember(member) == true)
            LoadData();

//load data method as follows
public void LoadData()
    {
        List<Member> members = memberService.GetAllMembers();
        gvMembers.DataSource = members;
        gvMembers.DataBind();

推荐答案

System.Guid.NewGuid（）



http://msdn.microsoft.com/en-us/library/system.guid.newguid(v = vs.110）.aspx [ ^ ]

call

Guid id = Guid.NewGuid();

引用：

new Guid（）使得一个空全0-guid（00000000-0000-0000-0000-000000000000不是很有用）。



Guid.NewGuid（）使用一个独特的值制作一个实际的guid，你可能想要的。

new Guid() makes an "empty" all-0 guid (00000000-0000-0000-0000-000000000000 is not very useful).

Guid.NewGuid() makes an actual guid with a unique value, what you probably want.
