赋值错误 - 值不在预期范围内

Question

我试图在将 oracle 参数发送到数据库之前为其赋值，但是这个特定的 XMLTYPE 正在抛出
System.ArgumentException: 'Value does not fall within the expected range.'

我尝试了各种建议，但大多数都涉及重启笔记本电脑或 visual studio 设置等，我觉得这与 XDocument 的 XMLType 有关。但是，类似的代码在另一个解决方案中有效。

我的 C# 代码如下所示：

public static string SaveMyData(int myId, XDocument myData)
        {            
            try
            {
                OracleParameter[] parameters = new OracleParameter[3];
                parameters[0] = new OracleParameter() 
                {
                    ParameterName = "P_ID",
                    Value = myId,
                    OracleDbType = OracleDbType.Int16,
                    Direction = ParameterDirection.Input
                };             

                parameters[1] = new OracleParameter()
                {
                    ParameterName = "P_DATA",
                    Value = myData,
                    OracleDbType = OracleDbType.XmlType,
                    Direction = ParameterDirection.Input
                };

                parameters[2] = new OracleParameter()
                {
                    ParameterName = "P_RESULT",
                    OracleDbType = OracleDbType.Varchar2,
                    Direction = ParameterDirection.Output
                };

                string myresult = DataAccess.DataContext.GetInstance().Data.ExecuteProcWithParameter(UPDATE_MY_DATA, parameters)["P_RESULT"].ToString();

                return myresult;
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

myData 的值为：

<players>
  <player>
    <id>10101</id>
    <name>Ricardo Ferreira Rodrigues</name>
    <shirtnumber>1</shirtnumber>
    <position>Guarda Redes</position>
    <realteam>5</realteam>
  </player>
  <player>
    <id>10103</id>
    <name>Antonio Manuel</name>
    <shirtnumber>2</shirtnumber>
    <position>Defesa</position>
    <realteam>5</realteam>
  </player>
</players>

我什至尝试将 myData 更改为 XmlDocument，但这也不起作用。知道可能出了什么问题吗？

Answer 1

你能试试这个吗

    XMLString = "<players>
  <player>
    <id>10101</id>
    <name>Ricardo Ferreira Rodrigues</name>
    <shirtnumber>1</shirtnumber>
    <position>Guarda Redes</position>
    <realteam>5</realteam>
  </player>
  <player>
    <id>10103</id>
    <name>Antonio Manuel</name>
    <shirtnumber>2</shirtnumber>
    <position>Defesa</position>
    <realteam>5</realteam>
  </player>
</players>";


parameters[1] = new OracleParameter()
            {
                ParameterName = "P_DATA",
                Value = XMLString,
                OracleDbType = OracleDbType.XmlType,
                Direction = ParameterDirection.Input
            };

Answer 2

您需要 OracleXmlType 的实例而不是 XDocument 并将 XML 作为字符串参数传递 (mydata.ToString())

赋值错误 - 值不在预期范围内

Error on value assignment - Value does not fall within the expected range

c#

.net

xml

oracle

xmltype
