Question

有谁可以解释下面的错误是什么？我是asp.net编码的新手。

创建devExpress报告类文件时会发生此问题。是因为文件包含

this.dataSet1.DataSetName = "DataSet";
this.dataSet1.SchemaSerializationMode = System.Data.SchemaSerializationMode.IncludeSchema;

描述：执行当前Web请求期间发生了未处理的异常。请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息。

异常详细信息：System.Runtime.Serialization.SerializationException：找不到成员'XmlSchema'。

*错误在第51行。

**Line 51:         string strSchema = ((string)(info.GetValue("XmlSchema", typeof(string))));**
Line 52:         if ((this.DetermineSchemaSerializationMode(info, context) == global::System.Data.SchemaSerializationMode.IncludeSchema)) {
Line 53:             global::System.Data.DataSet ds = new global::System.Data.DataSet();
