在我的情况下，我是不匹配的DSN.但这里是完整的解决方案：
当您通过Azure Active Directory连接时，在其他情况下，您必须指定UID、密码或PAT（个人访问令牌）。
要获取主机、httpPath和配置详细信息，请执行以下操作：https://learn.microsoft.com/en-us/azure/databricks/integrations/jdbc-odbc-bi#--install-and-configure-the-odbc-driver-for-linux
Docker命令：

FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS runtime
WORKDIR /app

RUN apt-get update

RUN apt-get install wget -y  && wget https://databricks-bi-artifacts.s3.us-east-2.amazonaws.com/simbaspark-drivers/odbc/2.6.29/SimbaSparkODBC-2.6.29.1049-Debian-64bit.zip
RUN apt-get install zip libsasl2-modules-gssapi-mit unixodbc gawk -y
RUN unzip SimbaSparkODBC-2.6.29.1049-Debian-64bit.zip && rm SimbaSparkODBC-2.6.29.1049-Debian-64bit.zip
RUN dpkg -i simbaspark_2.6.29.1049-2_amd64.deb 
RUN export ODBCINI=/etc/odbc.ini SIMBASPARKINI=/opt/simba/spark/lib/64/simba.sparkodbc.ini

#To setup DSN in /etc/odbc.ini file
RUN gawk -i inplace '{ print } ENDFILE { print "[ODBC Data Sources]" }'  /etc/odbc.ini
#Below DSN name should be same in below line and code, through this name it finds the driver
RUN gawk -i inplace '{ print } ENDFILE { print "Simba Spark ODBC DSN=Simba Spark ODBC Driver" }'  /etc/odbc.ini
RUN gawk -i inplace '{ print } ENDFILE { print "[Simba Spark ODBC DSN]" }'  /etc/odbc.ini

在C#中：DSN名称应与docker命令中的名称相同：
