mysql - 我的 SQL 在不应该 O.o 的情况下转换为 Int

Question

好的，我在从程序更新 SQL 记录时收到以下错误:

An unhandled exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll

Additional information: Conversion failed when converting the nvarchar value 'Full Member' to data type int.

这是更新代码； (我已经标记了引用包含 TEXT 的文本框的两个点，但无缘无故地试图转换为 INT。

Public Class EditSelected
Dim con As SqlConnection
Dim stcon As String
Dim cmd As SqlCommand
Dim ds As DataSet
Dim da As SqlDataAdapter

.

Private Sub EditSelected_Load(sender As Object, e As EventArgs) Handles MyBase.Load    
stcon = "{Censored Connection String}"
        con = New SqlConnection(stcon)

        con.Open()


        cmd = New SqlCommand("UPDATE PersonsA SET Members_ID=@id, Gamer_Tag=@gt, " & _
        "Screenname=@screen, First_Name=@first, Last_Name=@last, DoB=@dob," & _
        "E_Mail_Address=@email, Position=@pos, U_G_Studio=@ustudio, Cautions=@caution," & _
        "Record=@record, Event_Attendance=@event, Member_Status=@memstatus, " & _ '<---ERROR HERE
        "GTA_V_Crew_Member=@gtva, Games_Owned=@gameowned, Rep_Group=@repgroup " & _
        "WHERE Members_ID=@id", con)

        cmd.Parameters.AddWithValue("@id", midtxt.Text)
        cmd.Parameters.AddWithValue("@gt", gttxt.Text)
        cmd.Parameters.AddWithValue("@screen", sntxt.Text)
        cmd.Parameters.AddWithValue("@first", fntxt.Text)
        cmd.Parameters.AddWithValue("@last", lntxt.Text)
        cmd.Parameters.AddWithValue("@dob", dobtxt.Text)
        cmd.Parameters.AddWithValue("@email", emailtxt.Text)
        cmd.Parameters.AddWithValue("@pos", teamptxt.Text)
        cmd.Parameters.AddWithValue("@ustudio", ugptxt.Text)
        cmd.Parameters.AddWithValue("@caution", ugctxt.Text)
        cmd.Parameters.AddWithValue("@record", recordtxt.Text)
        cmd.Parameters.AddWithValue("@event", eventatxt.Text)
        cmd.Parameters.AddWithValue("@memstatus", memberstatcombo.Text) '<---ERROR HERE
        cmd.Parameters.AddWithValue("@gtva", gtavcrewmembercombo.Text)
        cmd.Parameters.AddWithValue("@gameowned", gamesownedtxt.Text)
        cmd.Parameters.AddWithValue("@repgroup", RepGroupcombo.Text)
        cmd.ExecuteNonQuery()
        MsgBox("Data has been saved!")

        da = New SqlDataAdapter("SELECT * FROM PersonsA", con)
        ds = New DataSet
        da.Fill(ds, "PersonsA")

        LeadersAccessTable.DataGridView1.DataMember = "PersonsA"
        LeadersAccessTable.DataGridView1.DataSource = ds

        con.Close()

我的 SQL 列“Member_Status”的数据类型为 varchar(35) 并且可为空。

这是怎么回事；为什么它试图将其转换为整数？

我提供了表列及其数据类型的屏幕截图 - 来自 SQL Management Studio 的屏幕截图。

糟糕，这取决于我的其他代码，它用所选索引的数据填充字段。事实证明，“正式成员”实际上并不在正确的文本框中，因此被发送到 INT 列之一。调试器应该更明显一点:/感谢您的帮助!
