我正在尝试使用dmcs(和gmcs ......我尝试过两者)从here编译以下示例:
using System;
using System.Data;
using Mono.Data.Sqlite;
public class Example
{
static void Main()
{
string cs = "URI=file:test.db";
using( SqliteConnection con = new SqliteConnection(cs))
{
con.Open();
DataTable table = new DataTable("Friends2");
DataColumn column;
DataRow row;
column = new DataColumn();
column.DataType = System.Type.GetType("System.Int32");
column.ColumnName = "Id";
table.Columns.Add(column);
column = new DataColumn();
column.DataType = Type.GetType("System.String");
column.ColumnName = "Name";
table.Columns.Add(column);
row = table.NewRow();
row["Id"] = 1;
row["Name"] = "Jane";
table.Rows.Add(row);
row = table.NewRow();
row["Id"] = 2;
row["Name"] = "Lucy";
table.Rows.Add(row);
row = table.NewRow();
row["Id"] = 3;
row["Name"] = "Thomas";
table.Rows.Add(row);
string sql = "SELECT * FROM Friends2";
using (SqliteDataAdapter da = new SqliteDataAdapter(sql, con))
{
using (new SqliteCommandBuilder(da))
{
da.Fill(table);
da.Update(table);
}
}
con.Close();
}
}
}
我使用了以下CL args来尝试编译它:
dmcs sqlite8.cs -r:Mono.Data.Sqlite.dll, System.Data.dll
gmcs sqlite8.cs -r:Mono.Data.Sqlite.dll, System.Data.dll
以下错误表现出来:
sqlite8.cs(2,14): error CS0234: The type or namespace 'Data' does not exists in the namespace 'System'. Are you missing an assembly reference?
或
error CS2001: Source file 'System.Data.dll' could not be found
Compilation failed: 1 error(s), 0 warnings
所以Mono找不到System.Data引用。我该怎么做才能解决这个问题?我习惯做C#,但CLI Mono编译对我来说是新的。
答案 0 :(得分:4)
您无法使用单个-r
选项传递多个程序集,您必须为每个引用提供-r
,例如:
mcs sqlite8.cs -r:Mono.Data.Sqlite.dll -r:System.Data.dll
请注意,错误提及“源文件”。
