将Guid值分配给C＃变量，即字符串

Question

我正在尝试捕获GUID值并存储在字符串变量中但获取空值

模型

public string StudentRemediationSignatureCheckGuid { get; set; }

ContextSession给我GUID值，我想将其分配给上面的变量

_assessmentRemidationObject.StudentRemediationSignatureCheckGuid = ContextSession.GUID.ToString(); 

更新代码

  public string SeniorAssessorGuid = string.Empty; //global variable


 protected void checkBoxSeniorAssessorSignature_CheckedChanged(object sender, EventArgs e)
    {
        CheckBox SelectedCheckBoxObject4 = (CheckBox)sender;

        if (SelectedCheckBoxObject4.Checked)
        {

            TxtBoxSeniorAssessorSignatureDate.Text = System.DateTime.Now.ToString("d/M/yyyy");

            _assessmentRemidationObject.SeniorAssessorSignatureCheckGuid = ContextSession.GUID.ToString(); 
            SeniorAssessorGuid = ContextSession.GUID.ToString(); 
        }
        else if (!SelectedCheckBoxObject4.Checked)
        {
            TxtBoxSeniorAssessorSignatureDate.Text = string.Empty;

        }
    }

如果您丢失其值，请不要将ContextSession.GUID的值存储在您网页_assessmentRemidationObject的成员中。您需要使用全局变量或持久存储（例如数据库）。在阅读之前，请尝试找到重置_assessmentRemidationObject的位置。
