这是我在Visual Studio中连接到Unity3d的代码:
public void SetupSQLConnection()
{
Debug.Log("Connection Function Started");
if (connection == null)
{
Debug.Log("If connection == null");
try
{
Debug.Log("Try block started");
string connectionString = "Server=localhost;" + "Database=therapygame;" + "UID=root;" + "Password=;";
Debug.Log("string set");
connection = new MySqlConnection(connectionString);
Debug.Log("new MySqlConnection");
connection.Open();
Debug.Log("connection");
}
catch (MySqlException ex)
{
Debug.LogError("MySQL Error: " + ex.ToString());
}
}
}
控制台字符串将一直打印到“字符串集”,但是其余的将不会打印。
这是Unity中的错误:
KeyNotFoundException:给定的密钥不存在于
字典。
System.Collections.Generic.Dictionary`2 [System.String,System.Object] .get_Item
(System.String键)(在
/Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Collections.Generic/Dictionary.cs:150)
MySql.Data.MySqlClient.MySqlConnectionStringBuilder.get_Database()
MySql.Data.MySqlClient.MySqlConnection.set_ConnectionString
(System.String值)MySql.Data.MySqlClient.MySqlConnection..ctor
(System.String connectionString)(包装带检查的远程调用)
MySql.Data.MySqlClient.MySqlConnection:.ctor(字符串)
mysql.SetupSQLConnection()(位于Assets / mysql.cs:31)fire_rate.Start()
(位于Assets / fire_rate.cs:18)
最佳答案
尝试这个
MySqlConnectionStringBuilder connBuilder = new MySqlConnectionStringBuilder();
connBuilder.Server = "localhost";
connBuilder.UserID = "root";
connBuilder.Database = "therapygame";
connBuilder.Password = "";
connBuilder.OldGuids = true;
connection = new MySqlConnection(connBuilder.ConnectionString);
关于c# - MySqlConnection =新的MySqlConnection(字符串)不起作用,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/55145945/
